Q1. A 7N horizontal force F pushes a block weighing 10.0 N against a vertical wall. The coefficient of static friction between the wall and the block is 0.74, and coefficient of kinetic friction is 0.540. Suppose that the block is not moving initially.
Q2. A hawk is flying horizontally at 17.0m/s in a straight line, 160 m above the ground. A mouse it has been carrying struggles free from its grasp. The hawk continues on its path at the same speed for 2.00s before attempting to retrieve its prey. To accomplish the retrieval, it dives in a straight line at constant speed and recaptures the mouse 3m above the ground. Hint: From the hawk's point of view, what is the motion of mouse? Does the hawk have to change both components of its motion to catch the mouse? Do part (c) initial, before the other parts.
