2. A batsman deflects a ball by an angle 45 degree without changing its initial speed which is equal to 54km/hr.What is the impulse imparted to the bal.(mass of the ball is .15kg)

**drwls**, Tuesday, August 14, 2012 at 4:05pm1. What system? Is there a figure that goes with this question?

2. Convert the 54 km/h speed to 15.0 m/s. Compute the velocity change vector.

Multiply that by 0.15 kg for the momentum change, which equals the impulse.

54 km/h is a VERY slow pitch (33.5 mph). A 45 degree deflection would be a foul tip.
