A 2000 kg car is being pushed from rest by a bulldozer. The car is pushed for 10 seconds along a rough road with a coefficient of friction of 0.05. The car experiences impulse of 10,000 kgm/s. a. What net force acts on the car? b. What is the acceleration of the car? c. What is the work done by the non-conservative forces as the car moves along the road? acar

I. A lump of clay (m = 3.00 kg) is thrown towards a wall at speed v = 3.00 m/s. The lump sticks to the wall. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. II. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not?
