STANDARD Physics Vertical Motion MCQ Question
Type: MCQ-numerical-Medium
In the previous question, the time taken by the ball to reach the ground is
A
2 s
B
3 s
C
5 s
D
7 s
Correct Answer
Option C
Detailed Explanation
Time to reach the highest point t₁ = 2 s. For downward motion: u = 0, a = 10 m s⁻², S = 45 m. Using S = ut + ½at², we find t₂ = 3 s. Total time = t₁ + t₂ = 5 s.
