Question: A mass of 100 𝑔 strikes the wall with speed 5 𝑚/𝑠 at an angle as shown in figure and it rebounds with the same speed. If the contact time is 2 × 10−3 sec, what is the force applied on the mass by the wall

(A) 250 $\sqrt{3}$ 𝑁 to right

(B) 250 𝑁 to right

(D) 250 𝑁 to left

Answer: Option (C)

Solution:

A mass of 100 𝑔 strikes the wall with speed 5 𝑚/𝑠 at an angle as shown in figure and it rebounds with the same speed. If the contact time is 2 × 10−3 sec, what is the force applied on the mass by the wall
