Question

(20 points) The horizontal and vertical components of the initial velocity of a golf ball are 60.4 m/s and 72.0 m/s respectively.

1. A) Sketch the motion of the ball and draw a motion diagram for the vertical and horizontal components of the motion.

2. B) List all known variable and their values.

3. C) If there is no air resistance, how long does it take the ball to reach the top of its trajectory?

4. D) Whatisthemaximumheightiftheballstartedatgroundlevel?

5. E) How far down the field has the ball traveled when it is at its maximum height?

6. F) If the course were on a planet where the free fall acceleration is 28 m/s2, what would the

   maximum height be?
