Help me with the following physics question:

5A Worksheet: Week 2 1. In this problem, Alice (A) is throwing a baseball to Bob (B). I, II, and III are points along the baseball's trajectory, where II is at the maximum height of the throw. Assume air resistance is negligible, and that gravitational acceleration is g = 9.8m/$2. (a) What is the acceleration of the ball of the ball at point I? What about at points II and III? (b) Suppose Alice throws with initial velocity Ux = 20m/s and Vy = 20m/s. Draw the velocity vector of the ball at A. How many seconds does the ball take to reach Bob? (Hint: Ay = 0 over the course of the entire throw) (c) How far does the ball travel horizontally? (i.e. find d) (d) What is Vx and Vy at point II, the peak of the throw? (e) How high is the ball off the ground at II? (i.e. find h) (f) What is vr and vy right before Bob catches the ball? Draw the velocity vector at B. II III h - A B a M / a
