at 1.4 m, traveling at 0.4 m/s. What is the acceleration due to friction, the frictional force and

the work done by friction? What is the change in kinetic energy of the cart?

b) If a cart of mass 0.6 kg, traveling a 0.5 m/s collides elastically with a cart of mass 0.4 kg,

initially at rest, what is the final velocity of the first cart?

c) If the two carts above stick together after the collision, what is the final velocity of the first

cart?

d) What is the final velocity of the first cart in (b) if the second cart has mass 1.5 kg?

e) What is the final velocity of the first cart in (c) if the second cart has mass 1.5 kg?
