A test car is driving toward a solid crash-test barrier with a speed of 45 mi/h. Two seconds prior to impact, the car begins to brake, but it is still moving when it hits the wall. After the collision with the wall, the car crumples somewhat and comes to a complete stop. In order to estimate the average force exerted by the wall on the car, what information would you need to collect? a. The (negative) acceleration of the car before it hits the wall and the distance the car travels while braking. b. The (negative) acceleration of the car before it hits the wall and the velocity of the car just before impact. c. The velocity of the car just before impact and the duration of the collision with the wall. d. The duration of the collision with the wall and the distance the car travels while braking.

Slanted surfaces without friction: A block is given a very brief push up a 20.0° frictionless incline to give it an initial speed of 12.0 m/s.(a) How far along the surface of the plane does the block slide before coming to rest?(b) How much time does it take to return to its starting position?
A 1400 kg car, starting from rest, accelerates to a speed of 30 mph in 10 s. (a) What is the force on the car (assumed constant) during this time period? (b) Where does this force come from, that is, what is the (external) object that exerts this force on the car and what is the nature of this force?is responsible for providing the energy necessary to turn the wheels, but without an interaction with the external environment, there would be no motion). (c) Draw a free-body diagram for the car. Indicate the direction of motion and the direction of acceleration. Now suppose that the driver, traveling at 30 mph, sees a red light ahead and pushes the brake pedal. Assume that the coefficient of static friction between the tires and the road is µe = 0, 7, and that the wheels do not "lock up," that is, they continue to roll without slipping on the road as the speeddecreases. (d) Draw a free-body diagram of the car and (e) determine the minimum stopping distance of the car? Again, indicate the…
