A 0.144kg baseball is pitched horizontally at 38.0 m/s. After the baseball is hit by the bat, it moves at the same speed, but in
Hoochie [10]

Answer:

Given:

mass of the ball m = 0.144 kg

velocity v = 38 m/s

now,  change in momentum

P = m v- ( - mv)

  = 2 mv

  =2 x (0.144) x (38)

  = 10.944 kg-m/s

Impulse J= F. Δt

change in momentum is equal to impulse

J = 10.944 kg-m/s

we know force is equal to change in momentum per unit time

F = \dfrac{P}{t}

F = \dfrac{10.944}{0.8\times 10^{-3}}

F = 13.68 x 10³ N

F = 13.68 kN
