Question

In a Little League baseball game, the 145 g ball reaches the batter with a speed of 15.0 m/s. The batter hits the ball, and it leaves his bat with a speed of 20.0 m/s in exactly the opposite direction. What is the magnitude of the impulse delivered by the bat to the ball

Answer: 5.075Ns

Explanation:

Given the following :

Mass of ball = 145g

Initial Speed of ball = 15m/s

Final speed of ball when hit by the batter = – 20m/s ( Opposite direction)

The impulse of a body is represented using the relation:

Force(f) * time(t) = mass (m) * (final Velocity(V) – initial velocity(u))

Therefore, using:

m(v – u) = impulse

Mass of ball = 145 / 1000 = 0.145kg

Impulse = 0.145(- 20 – 15)

Impulse = 0.145(-35)

Impulse = 5.075Ns
