1. You throw a ball straight up. You are feeling extra strong today. It takes 11 seconds for the ball to come back down. a. How high did you through it?

b. What was the initial speed you threw it at?

2. You drop a large rock from a 19 story building. It is 78 meters high. The wind is blowing from the southwest at 3.5 m/s.

What is the initial velocity of the rock?

How long will it take to hit the pile of leaves that are sitting below?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
