F = mg + ma F = (1200)(9.8) + (1200)(0.90) F = (1200)(9.8 + 0.9)
To calculate the tension in the rope, you need to consider the force needed to overcome the gravitational force on the car plus the force required to accelerate the car. The tension in the rope can be found using the equation T = mg + ma, where T is the tension, m is the mass of the car, g is the acceleration due to gravity, and a is the acceleration of the car. In this case, the tension in the rope would be T = (1600 kg * 9.8 m/s^2) + (1600 kg * 0.70 m/s^2).
it depends on how long the car will have to withstand that acceleration since there are also other factors like atmospheric drag. First second: kg = kilogram N = Newton 1kg = 9,81N 1800kg = 17.658N Force on the rope: 17658.0 x 0,6 = 10.594,8N = 10.595N 10.595N / 9,81 = 1080kg Your rope must withstand at least 1080kg or 10.595N for the first second.

The forces acting on a hanging pen are gravitational force pulling it downward and tension force in the string supporting it. The gravitational force acts vertically downward on the pen due to Earth's gravity, while the tension force in the string acts vertically upward to counterbalance the weight of the pen.
Vertical means straight up and down,aligned with the direction of gravity. Vertically upward means vertical in the up direction. So if you jump directly straight up that is vertically upward; when you land you are travelling vertically downward.
because if gravity
An object projected vertically upward in free fall essentially means it is given an initial velocity upward and then left to fall freely under the influence of gravity. As it moves upwards, its velocity decreases until it reaches the highest point and then starts to fall back due to gravity. During this motion, the only force acting on the object is gravity, causing it to accelerate downward at a rate of 9.8 m/s^2.
UPWARD UPWARD UPWARD
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
Air pressure exerts a vertically upward force on a ceiling due to the weight of the air above pushing down on the air below. This pressure difference results in a net force that pushes upward on the ceiling, according to Newton's third law of motion.
To lift a 78 pound person into the air with a constant velocity, you would need to exert a force equal to 78 pounds (the weight of the person) in the upward direction. This force is required to counteract the force of gravity acting on the person.
The direction of acceleration would be vertically upward, since the net force is acting in that direction. The horizontal motion of the balloon being blown westward does not affect the acceleration in the vertical direction.
