A baseball (m = 0.14 kg) thrown by a pitcher reaches a bat with a velocity of 32.0 m/s in a horizontal direction.
a) Computer the impulse that must be applied to the ball if it is to leave the bat with an initial velocity of 47.0 m/s, directed 40˚ above the horizontal direction?
b) Find the average force acting on base ball in the 2 x 10-3 s intervals during which it is in contact with bat?
According to the impulse-momentum theorem, the impulsive applied to the ball equals it change in momentum
We express this equation for component form for horizontal direction as
Find impulsive applied on vertical direction
Impulsive magnitude
Impulsive direction
Θ = 82.46˚
Average force acting on the ball in the 2 x 10-3 s intervals is
Average force acting on the ball 9100 N.
