Physics-Impulse & Momentum
NEET Physics Impulse & Momentum MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram where a ball of mass m moving with velocity v strikes a wall at an angle θ and rebounds with the same speed at the same angle. Which of the following represents the magnitude of the impulse imparted by the wall to the ball?
A
2mv cos θ
B
mv sin θ
C
2mv sin θ
D
mv cos θ
Correct Answer
Option A
Detailed Explanation
When the ball rebounds with the same speed and angle, the change in momentum in the direction perpendicular to the wall is 2mv cos θ, reflecting the impulse imparted by the wall.
