What is the impact velocity of a rock thrown horizontaly from a cilff?
The impact velocity of a rock thrown horizontally from a cliff will depend on the height of the cliff and the initial velocity at which it was thrown. If air resistance is neglected, the velocity of impact will be equal to the horizontal component of the initial velocity.
What is the acceleration of an object thrown 3.5 meters at 44 meters per second?
The acceleration of an object thrown vertically upwards can be calculated using the kinematic equation (v_f^2 = v_i^2 + 2a \cdot d), where (v_f) is the final velocity, (v_i) is the initial velocity, (a) is the acceleration, and (d) is the distance. Given that the object is thrown vertically upwards, the equation becomes (0 = (44 , \text{m/s})^2 + 2 \cdot a \cdot (-3.5 , \text{m})). Solving for (a), we find that the acceleration is approximately -104 m/s², which indicates that the object is accelerating downwards.
If a moving body has no acceleration does it mean that no force is acting on it?
It means there is no net force acting on it. A plane in the air has no acceleration, but it does have forces acting on it. Lift pushes it up Gravity pushes it down Air resistance opposes its movement Thrust provides movement When all these forces are equal the plane will move at a constant velocity. If one of these forces becomes greater the NET force on the plane will no longer be 0 and there will be an acceleration or deceleration. Hope that helps. Another example would be space as there are no opposing forces, if in space once a speed was that speed would be constant until you 1.) decelerated with a force in the opposite direction 2.) accelerated the speed past your current velocity in your current direction 3.) Get caught by some planets gravity and crash to you death (but then this question is the least of your problems)
Is it possible for a body to have zero velocity and non-zero acceleration?
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
A juggler throws a bowling pin into the air with an initial velocity Vi another juggler drops a pin at the same instant compare the accelerations of the two pins while they are in the air?
Since the question is asking you to compare the acceleration after the pins have been released, the only force acting on each pin is gravity. Therefore, the acceleration on both pins is the acceleration due to gravity, or 9.8 m/s2 towards the earth. Even though one of the pins is being thrown up, once released, the acceleration is still 9.8 m/s2 towards the earth.Each pin has the same acceleration.
Explain the difference between positive and negative acceleration?
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
If a softball was thrown 40feet and 8 inches how many inches was the softball thrown?
488 inches
Why it is taken as negative when an object is thrown upwards against gravitation?
When we throw the object upwards we consider that upward direction as positive. Therefore, the velocity in that direction is positive but the acceleration due to gravity is in the opposite direction and so it is considered negative. But when the ball comes down again after reaching a certain height the velocity is in opposite direction to the earlier one and so the velocity now is negative as a result the acceleration is again negative.
When is acceleration due to gravity positive and when is it negative?
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
When thrown by the same person which can be thrown farther a baseball or a softball?
A baseball can
If after an object is thrown no other fone and ads on it except gravity What are the vertical and horizontal components of its acceleration vector?
The vertical component of the acceleration vector is the acceleration due to gravity (9.81 m/s^2 downward). The horizontal component of the acceleration vector is zero since there is no acceleration acting in the horizontal direction (assuming no external forces).
If a ball is thrown vertically upwards and the acceleration on it is neg 9.8 due to gravity will the sign change when the ball changes direction to fall back down thus giving an acceleration of 9.8?
Yes. On the way up, negative acceleration is taking place because the ball is moving up and gravity is acting in the opposite direction. On the way back down, acceleration is positive, and the object starts at rest.
What Negative acceleration definition with examples?
Negative acceleration, also known as deceleration, occurs when an object slows down due to an opposing force acting against its motion. For example, a car braking to come to a stop or a ball thrown upwards reaching the peak of its trajectory experience negative acceleration. It is quantified by a decrease in velocity over time.
In softball what is a force?
A force is when there is an automatic out at the base if the ball is thrown there
Is the acceleration the same on an object that is drop or when its thrown?
No, the acceleration is not the same for an object that is dropped and an object that is thrown. When an object is dropped, it experiences a constant acceleration due to gravity. When an object is thrown, its acceleration can vary depending on factors such as the initial velocity and direction.
Initial velocity of a softball thrown at 30 mph?
30 mph!
What does pit mean in softball stats?
PIT is pitches thrown or pitch count.
