A mass of 100g strikes the wall with speed 5m/s at an angle as shown in figure and it rebounds with the same speed. If the contact time is 
, what is the force applied on the mass by the wall
A
N to right
B
250 N to right
C
N to left
D
250 N to left
Text Solution
Verified by ExpertsThe correct answer is:
C
Force = Rate of change of momentum
Initial momentum 
Final momentum 
∴ ∴ 
Substituting m = 0.1 kg, v = 5 m/s, θ θ = 60°
Force on the ball 
Negative sign indicates direction of the force
