Type: MCQ-numerical-Medium-Class 11
A body of mass 3 kg hits a wall at an angle of 60° & returns at the same angle. The impact time was 0.2 s. Calculate the force exerted on the wall:
A
150√3 N
B
50√3 N
C
100 N
D
75√3 N
Correct Answer
Option A
Detailed Explanation
The change in momentum is calculated using the initial and final velocities. The force is the change in momentum divided by the impact time, resulting in 150√3 N.
