Physics-Impulse & Momentum
NEET Physics Impulse & Momentum MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a scenario where a ball of mass 0.05 kg strikes a wall with a velocity of 6 m/s and rebounds with the same speed. Which of the following correctly represents the impulse imparted to the ball by the wall?
A
0.6 N·s in the direction opposite to the initial velocity
B
0.3 N·s in the direction of the initial velocity
C
0.6 N·s in the direction of the initial velocity
D
0.3 N·s in the direction opposite to the initial velocity
Correct Answer
Option A
Detailed Explanation
The impulse is the change in momentum, calculated as mass × change in velocity. Here, the change in velocity is 12 m/s (since it rebounds with the same speed in the opposite direction), giving an impulse of 0.6 N·s.
