Questions 16-20 refer to the following situation: A heavy semi-truck collides head-on with a small, light car \(\left(m_{\text {car }}<m_{\text {truck }}\right)\). Before the collision the vehicles were moving with the same speed but in opposite direction.During the collision, is the force that the car exerts on the truck greater, equal or less than the force that the truck exerts on the car?There is not enough information to determine the answer.It is greater than the force exerted by the truck...

A truck moving at 35.0 mph collides head on with a car traveling in the opposite direction. The mass of the car is 550 kg, the mass of the truck is 2200 kg. During the collision both vehicles come to a stop in 0.150 s as the front end of both vehicles’ crumples. What was the acceleration of the car? Assume that during the collision the acceleration of each vehicle is constant. Also, assume that frictional force are small compared...
