Question

A baseball player hits a baseball with a bat, changing both the speed and direction of the baseball. The baseball has a mass of 0.16kg and its speeds before and after the hit are 15m/s and 10m/s. If the hit lasts 0.023s, a. What is the change in momentum of the baseball? b. What is the average force exerted on the ball by the bat?

Answer #1

A baseball player swings his 1kg bat at 10m/s as he hits a 60g
baseball that is coming at him at 20m/s. The ball bounces of his
racket at 38m/s.
(a) Draw a before/after picture showing
velocities/directions.
(b) How fast is his bat moving after the collision? In what
direction? If the bat and ball are in contact for only 10ms, what
is the average force on the ball during the collision?

The ball hits by a baseball player makes the baseball bat 0.9
above the ground, 61 ° to the horizontal.
it leaves with an initial velocity of 28 ? / ? upwards. Neglecting
air resistance
a) If the ball is not caught, find out how far it has traveled
horizontally and then landed.
b) Standing at the point where the ball was hit and 2 second after
the ball was kicked
just before the ball of another player starting to...

A major leaguer hits a baseball so that it leaves the bat at a
speed of 29.0 m/s and at an angle of 35.0o above the horizontal.
You can ignore air resistance. a. At what two times is the baseball
at a height of 11.6 m above the point at which it left the bat? b.
The ball hits a sign 72.0 m from the batter. If the bat hit the
ball when it was 2.0 m above the ground,...

A soccer player hits a 0.20 kg ball which is incoming
with a speed 5 m/s. After the kick, the ball changes its direction
by 90 degrees and keeps its original speed. What is the average
force exerted by the player if the impact time is 0.02
seconds?

A baseball approaches home plate at a speed of 47.0 m/s, moving
horizontally just before being hit by a bat. The batter hits a
pop-up such that after hitting the bat, the baseball is moving at
52.0 m/s straight up. The ball has a mass of 145 g and is in
contact with the bat for 1.80 ms. What is the average vector force
the ball exerts on the bat during their interaction?

A baseball approaches home plate at a speed of 38.6 m/s, moving
horizontally just before being hit by a bat. The batter hits a
pop-up such that after hitting the bat, the baseball is moving at
49 m/s straight up. The ball has a mass of 164 g and is in contact
with the bat for 1.55 cs. What is the average force the ball exerts
on the bat during their interaction?
F = N i and N j.

A baseball with a mass of 153 g is thrown horizontally with a
speed of 40.7 m/s (91 mi/h) at a bat. The ball is in contact with
the bat for 1.00 ms and then travels straight back at a speed of
45.8 m/s (102 mi/h). Determine the average force exerted on the
ball by the bat. Neglect the weight of the ball (it is much smaller
than the force of the bat) and choose the direction of the incoming...

A baseball with a mass of 147.2 g is thrown horizontally with a
speed of 44.6m/s at a bat. The ball is in contact with the bat for
1.379 ms and then travels straight back at a speed of 49.7.
Determine the average force exerted on the ball by the bat. Neglect
the weight of the ball (it is much smaller than the force of the
bat).
