Q1. After a 0.360 kg rubber ball is dropped from a height of 2 m, it bounces off a concrete floor and rebounds to a height of 1.35 m.

Determine the magnitude and direction of the impulse delivered to the ball by the floor.

Q2. A 282 kg log is pulled up a ramp by means of the rope that is parallel to the surface of the ramp. The ramp is inclined at 23.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.87, and the log has an acceleration of 0.70 m/s2. Find out the tension in the rope.
