Question

A ball is thrown vertically upward, it returns to the level from which it started in 2.1 seconds. What is the initial velocity of the ball in m/s?

give your answer as a positive value

Answer 1

If a ball is thrown vertically upwards with an initial velocity V 0 then here is a set of formula for your quick reference. 1) Maximum height reached = H = V 02 / (2 g) 2) Velocity at the highest point = 0 3) Time for upward movement = V 0 /g 4)
