A ball collides with a stationary toy train carriage. The velocity of the ball decreases from 1.2 m sā1 to the right to 0.10 m sā1 to the right.
The carriage then collides with a stationary toy locomotive. The carriage and locomotive join together.
Calculate the speed in m sā1 of the locomotive and train carriage immediately after the second collision.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
