Question

A ball is thrown vertically upwards with an initial velocity of 20 m/s. Calculate the time it takes for the ball to reach the highest point. (Assume \( g = 9.8 \, \text{m/s}^2 \))

• A. \( 2.04 \, \text{s} \)
• B. \( 1.8 \, \text{s} \)
• C. \( 3.0 \, \text{s} \)
• D. \( 4.0 \, \text{s} \)

Hint:

At the highest point, the velocity of a vertically thrown object becomes zero. The time to reach the highest point is simply the time taken for the velocity to reduce to zero under the influence of gravity.
