Question

A ball of mass m is moving towards a batsman at a speed v. The batsman strikes the ball and deflects it by an angle qwithout changing its speed. The impulse imparted to the ball is given by :

• A. 2mv cos$\left( \frac{\theta}{2} \right)$
• B. 2mv sin$\left( \frac{\theta}{2} \right)$
• C. 2 mv cos q
• D. 2 mv sin q

Answer 1

Answer: (A)

2mv cos$\left( \frac{\theta}{2} \right)$

Answer 2

Dp = 2mv cos$\left( \frac{\theta}{2} \right)$
