Question

Part A Find the magnitude of the impulse that the bat imparts to the ball. Express your answer in newton-seconds to three significant figures.

___________ Ns

Part B Find the direction of the impulse that the bat imparts to the ball. Find the direction of the impulse that the bat imparts to the ball.

a)to the right

b)to the left

Part C Find the magnitude of the ball's velocity just after it is hit by the bat if the ball is initially at rest. Express your answer in meters per second to three significant figures.

____________ m/s

Part D Find the direction of the ball's velocity just after it is hit by the bat if the ball is initially at rest. Find the direction of the ball's velocity just after it is hit by the bat if the ball is initially at rest.

a) to the right

b) to the left

Part E Find the magnitude of the ball's velocity just after it is hit by the bat if the ball is initially moving to the right at 30.0 m/s . Express your answer in meters per second to three significant figures.

___________ m/s

Part F Find the direction of the ball's velocity just after it is hit by the bat if the ball is initially moving to the right at 30.0 m/s . Find the direction of the ball's velocity just after it is hit by the bat if the ball is initially moving to the right at 30.0 .

a) to the right

b) to the left

Explanation / Answer

a) impulse = area of f-t graph

I = 4*3*10^-3 = 12*10^-3 kg m/s or Ns

b) right

c) impulse = chaneg in momentum

mv = I

v = 12*10^-3/0.146 = 0.0821 m/s

d) right

e) I = 0.146(v-30)

v= 30.08 m/s

right
