NEET Physics Speed & Velocity MCQ Question
Type: MCQ-diagram based-Medium-Class 11
A speed-time graph is plotted for a ball dropped from a height of 90 m. The ball loses one tenth of its speed at each collision with the floor. Which of the following statements correctly describes the graph between t = 0 to 12 s?
A
The graph shows a series of decreasing linear segments.
B
The graph shows a constant speed throughout the time interval.
C
The graph shows speed increasing uniformly after each bounce.
D
The graph shows a parabolic curve due to uniform acceleration.
Correct Answer
Option A
Detailed Explanation
The speed of the ball decreases by one tenth after each collision, leading to a series of decreasing linear segments on the speed-time graph.
