A ball is projected vertically upward at a speed of 50 m/s . Determine the time required to reach the maximum height in s. Take g = 10 m/s ^2 .

Step-by-step solution

Given initial velocity u = 50 m/s and acceleration due to gravity g = 10 m/s ^2 . At the maximum height, the final velocity of the ball becomes zero, so v = 0 . Using the first equation of motion v = u - gt : 0 = 50 - 10t 10t = 50 t = 5 s
