What is the relationship between skid length and the initial velocity of a car help answer this theorotically not in formula thnkx?
The skid length of a car is directly related to its initial velocity. A car traveling at a higher initial velocity will skid for a longer distance before coming to a stop compared to a car traveling at a lower initial velocity. This is because the higher initial velocity results in a greater kinetic energy that needs to be dissipated through braking, causing the car to skid for a longer distance.
If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
If you know the acceleration of a car its initial velocity the time interval what can you predict?
Its final velocity, the distance covered.
What is the acceleration of car that increase its speed by 10 milessec after 30 seconds if the initial velocity was 20 milessec?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.
How can the velocity of a car during breaking at a constant acceleration against time from the moment of applying the breaks?
The velocity of a car during braking with constant acceleration can be calculated using the kinematic equation: final velocity = initial velocity + acceleration * time. As the car brakes, the initial velocity decreases to 0 m/s (assuming the car comes to a stop), and the acceleration due to braking is negative. Therefore, the equation becomes: final velocity = -acceleration * time.
What to do if the car change its velocity and the given is the acceleration?
If the acceleration of the car is given, you can calculate the change in velocity using the formula: final velocity = initial velocity + (acceleration * time). You need to know the initial velocity and the time for which the acceleration is acting to determine the final velocity.
What happens to a car's velocity when you double its velocity?
Its value grows to become precisely equal to double its initial value, while its direction remains unchanged.
What is the car's acceleration between 25s and 30s?
The car's acceleration between 25s and 30s can be calculated by determining the change in velocity during that time interval and dividing it by the time elapsed. Acceleration = (final velocity - initial velocity) / time. You need to know the initial and final velocities of the car during that time period to calculate its acceleration.
Can the effect of initial velocity on final velocity be predicted?
Well, (final velocity) = (initial velocity) + (acceleration x time)
What is the final velocity f a car that accelerates from rest at 9ftsecond squared for 8 seconds?
The final velocity of the car can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Since the car starts from rest, its initial velocity is 0. Plugging in the values, we get: final velocity = 0 + (9 ft/s^2 * 8 s) = 72 ft/s. Therefore, the final velocity of the car is 72 ft/s.
When the initial velocity is zero?
When the initial velocity is zero, the object is at rest, and there is no motion in the direction of the velocity. This means that the object will not have any kinetic energy due to its velocity at the initial moment.
Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the acceleration.
