STANDARD Physics Free Fall MCQ Question
A player throws a ball upwards with an initial speed of 30 m s⁻¹. How long does the ball take to return to the player’s hands? (Take g = 10 m s⁻²)
3 s
6 s
9 s
12 s
Correct Answer
Detailed Explanation
The time taken by the ball to reach the highest point is calculated using v = u + at. Here, u = 30 m s⁻¹, v = 0, and a = -10 m s⁻². Solving gives t = 3 s to reach the highest point. The total time for the ball to return is 2 × 3 s = 6 s.
