Q1. 0.55 kg block of ice is sliding through you on the very slippery floor at 3.6 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 0.0065 seconds. The block eventually slides at an angle of 32 degrees from its original direction (labelled in the diagram). The overhead view is approximately to scale. The arrow represents the average force your toe applies briefly to the block of ice.
Q2. You are driving home from school steadily at 94 km/h for 150 km. It then begins to rain and you slow to 63 km/h. You arrive home after driving 3 hours and 30 minutes. How far your hometown from school and what is was your average speed?
