P111. Two-dimensional Kinematics Problems

Before doing these problems, be sure that you've studied the Guide for Solving Projectile Problems. In addition, here's another example problem solution. It's problem 31 of Chapter 4.

Part A

Download and print this template. Write your solution to the stated problem on the template.

Part B

Unless stated otherwise below, show your work using the same steps as on the template.

  1. Do Problem 34 of Chapter 4: In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 14 m/s at an angle of 34° above the horizontal. (a) How long does it take for the ball to reach the wall if it is 3.8 m away? (b) How high is the ball when it hits the wall?

  2. Problem 35 of Chapter 4: In the previous problem, (a) what are the magnitude and direction of the ball's velocity when it strikes the wall? (b) Has the ball reached the highest point of its trajectory at this time? Explain. (Note: Neither part of this problem requires the standard projectile problem-solving form. You'll take some information from the last problem and calculate something else about the motion. You are expected to draw a vector diagram showing the final velocity and its horizontal and vertical components.)
