Question

The number line shows the starting and ending velocities for ball 1. What’s the change in velocity of ball 1? Calculate the value mathematically, and check it using the number line.

Answer 1

The starting velocity for ball 1 is 1.00 meter/second. Its ending velocity is 0.25 meter/second.

The change in velocity for ball 1 is 0.25 – 1.00 = -0.75 meter/seconds

Answer 2

The starting velocity for ball 1 is 1.00 meter/second. Its ending velocity is -0.50 meter/second.

The change in velocity for ball 1 is -0.50 – 1.00 = -1.50 meters/second.
