Question

••An air-track cart of mass m1 = 0.14 kg is moving with a speed
v0 = 1.3 m>s to the right when it collides with a cart of mass
m2 = 0.25 kg that is at rest. Each cart has a wad of putty on its bumper, and hence they stick together as a result of their collision. Suppose the average contact force between the carts is F = 1.5 N during
the collision. (a) What is the acceleration of cart 1? Give direction
and magnitude. (b) What is the acceleration of cart 2? Give direction and magnitude. (c) How much time does it take for both carts
to have the same speed? (Once the carts have the same speed the
collision is over and the contact force vanishes.) (d) What is the final
speed of the carts, vf
? (e) Show that m1v0 is equal to 1m1 + m22vf
