Question

A player throws a ball upwards with an initial speed of $29.4	ext{ m/s}$. After how long does the ball return to the player's hands? (Take $g = 9.8	ext{ m/s}^2$)

Professor PC Thomas Classes · Answer

The time taken to reach the maximum height is $t = \frac{u}{g} = \frac{29.4}{9.8} = 3	ext{ s}$. The time of ascent equals the time of descent, so the total time of flight is $2t = 2 	imes 3 = 6	ext{ s}$.
