A 1-kg standard cart collides with a cart A of unknown inertia. Both carts appear to be rolling with significant wheel friction because their velocities change with time as shown in Figure P4.28.

(a) What are the carts' velocities at \(t=0, t=5.0 \mathrm{~s}, t=6.0 \mathrm{~s}\), and \(t=10 \mathrm{~s}\) ?

(b) When not colliding, are the carts speeding up or slowing down?

(c) Is the acceleration of each cart the same before and after the collision?

(d) What is the inertia of cart A?
