Q1. 0.75 kg block of ice is sliding by you on a very slippery floor at 2.5 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.003 seconds. The block eventually slides at an angle of 22 degrees from its original direction (labelled in the diagram). The overhead view is around to scale. The arrow represents the average force your toe applies briefly to the block of ice.

Q2. A race car can be slowed with a constant acceleration of -14 m/s2.

(a) If the car is going 44 m/s, how many meters will it travel before it stops?

(b) How many meters would it take to stop a car going twice as fast?
