Question

You throw a ball straight up into the air with velocity 40 ft/sec and catch it (at the same height) when it comes back down. What is the total distance traveled by the ball

Answer 1

The total distance traveled by the ball is determined as 49.68 ft.

Height travelled by the ball

The height travelled by the ball or the maximum height attained by the ball is calculated as follows;

v² = u² - 2gh

• at maximum height, v = 0

0 = u² - 2gh

2gh = u²

h = u²/2g

h = (40²)/(2 x 32.2)

h = 24.84 ft

Total distance = 2 x 24.84 ft = 49.68 ft
