Problem 7 - Entrance Test

A body is projected vertically upwards with a velocity of 19.6 m/s. Find the time taken to reach the highest point. (g = 9.8 m/s²)

Correct: B

At the highest point, the final velocity v = 0. Using the equation v = u - gt, we have 0 = 19.6 - 9.8t. Therefore, t = 19.6/9.8 = 2 s.
