## Problem 3.13: A putted golf ball rolls in a straight line toward the hole

The animation shows a putted golf ball as it travels toward the hole (position is given in meters and time is given in seconds). Restart.

1. Is the acceleration of the golf ball between t = 0 and t = 4.2 s constant, increasing, or decreasing?
2. What is the average acceleration of the golf ball during this time interval?
3. Calculate the x displacement of the golf ball from t = 0 to t = 4.2 s and show that it is the same as what you measure on the animation.
4. Calculate the y displacement of the golf ball from t = 0 to t = 4.2 s and show that it is the same as what you measure on the animation.
5. What is the magnitude of the displacement of the golf ball from t = 0 to t = 4.2 s?
