Question

1. A ball rolls with a constant acceleration of a = 2 m/s2 over 5 s and an initial velocity of 0 m/s. Calculate the ball’s distance from the starting point at 1.0 s intervals. Make a position-time graph for the object’s motion. In your response, show what you are given, the equation that you used, any algebra required, a table of data, and your graph.

Answer 1

Since the ball is accelerating, use the following equation to determine the distance it moves.

d = vi * t + ½ * a * t^2, vi = 0, a = 2
d = ½ * 2 * t^2 = t^2
d0 = 0
d1 = 1^2 = 1
d2 = 2^2 = 4
d3 = 3^2 = 9
d4 = 4^2 = 16
d5 = 5^2 = 25

When you graph the data, the graph will look like one half of a parabola. If you go to the website below you will see a graph like this one.
