Question

a batsman deflects a ball by an angle of 90 degree without changing its initial speed which is equals to 54 km per hour what is the impulse imparted to the ball mass of ball is 0.5 kg

Answer 1

Answer :

3.18 N-s

Given :

u = 54 km/hr = 15×5/18 = 15 m/s

m = 0.15 kg

∆p = 2mucos45°

∆p = impulse = 2×0.5×15×1/√2

= 3.18
