Question1

Car a is moving with a constant speed of 10m/s and passes car b which is at rest. Ten second later the latter follows with an acceleration of 0.5m/s^2. Establish the distance that the latter has to travel before it overtakes the former.

Question2

Red ribbon wound around a red spool (above) is taped to blue ribbon wound around a blue spool. The ribbon is essentially massless, but the solid cylindrical spools each have mass m and radius R. If the red spool can freely rotate on a set axle and the blue spool is positioned directly underneath with the ribbon taut, what is the downward acceleration of the blue spool? Gravity is downward.

Enter the reply in terms of some or all of the variables m, R and g.
