If a ball is thrown off the roof with a starting velocity of 10 mph and hits the ground at a final velocity of 30 mph, what is the average velocity of its descent?
The equation is:
Average velocity = (final velocity + initial velocity) \u00F7 2
Fill in the appropriate values:
Average velocity = (30 mph + 10 mph) \u00F7 2
Average velocity = 40 mph \u00F7 2 = 20 mph
