The center of mass of a car of mass M is located midway between the front- and rear wheels, at a distance h from the ground. The distance between the front and the rear wheels is d.

a) The car is moving forward on a horizontal surface with a constant acceleration A. In a system that is accelerating with the car, what can be said about the horizontal forces that is acting on the car?

b) What is the ratio between the normal force acting on the front- and rear wheels if the driver brakes with an acceleration g? Explain your answer.

c) Is your answer in b) dependent on the mass of the car? Why/why not?

1. To determine the location of the center of gravity of a car, the car is driven over a scale on a horizontal floor. When the front wheels are over the scale, the weight recorded by the scale is 5.79 x 103 N, and when the rear wheels are over the scale, the scale reads 6.51 x 103 N. The distance between the front and rear wheels is measured to be 3.20 m. How far behind the front wheels is...

A 1700-kg truck and a 1000-kg car are parked with their rear bumpers nearly touching each other in a level parking lot. Both vehicles have their brakes off so that they are free to roll. A man sitting on the rear bumper of the truck exerts a constant horizontal force on the rear bumper of the car with his feet, and the car accelerates at 1.2 m/s2. Ignore any friction between the tires and the parking lot surface. The direction...

Suppose you have a car traveling down the road at constant speed and not changing direction. It is experiencing gravity, wind resistance and frictional forces from the road. What can be said about the car's acceleration? Group of answer choices It is not accelerating because it has constant velocity. It accelerating because the motor is running, propelling the car forward. It is accelerating because there are forces acting on it. It is not accelerating because gravity holds it down.

A truck of mass M and a car of mass m are moving along a level roadway in opposite directions at the same velocity. The car and the truck are involved in a head-on collision. Assume that neither driver had time to apply the brakes before or during the collision. Immediately after the collision the two vehicles are stuck to each other, and the wheels are still rolling. Part 1 During the collision, the force on the car due to...

A racing driver negotiates a corner of radius 20 m at a speed of 8.5 m/s on level ground without slipping. The mass of the car is 600 kg and that of the driver is 91 kg. a. Calculate the total frictional force acting on the wheels as the corner is made. b. After this, the driver then negotiates a corner, which is banked at 30 degrees to the horizontal. The radius of this circular path is also 20 m....

4.) A cart with mass m = 1:2 kg touches a block with mass M = 7:3 kg. Both blocks sit on a horizontal surface; the wheel of the cart eliminates the friction with the surface; the coecient of kinetic friction between the block M and the surface is not known. The box and cart are initially at rest. a) We exert a horizontal push P = 63:3N and move the block-cart system through the distance s = 0:87 m....
