Question

A 0.160-kg baseball pitched horizontally at 37.0 m/s strikes a bat and is popped straight up to a height of 33.0 m . If the contact time between bat and ball is 2.5 ms , calculate the magnitude of the average force between the ball and bat during contact. Express your answer using two significant figures

Answer #1

A 0.165-kg baseball pitched horizontally at 38.0 m/s strikes a
bat and is popped straight up to a height of 33.0 m . If the
contact time between bat and ball is 1.0 ms , calculate the
magnitude of the average force between the ball and bat during
contact. Find the direction of the avg force on the ball ∘ from the
initial direction of motion of the ball.

A 0.145-kg baseball pitched horizontally at 31.8 m/s strikes a
bat and is popped straight up to a height of 56.2 m. If the contact
time is 1.80 ms, calculate the magnitude of the average force on
the ball during the contact. Calculate the direction of the average
force on the ball during the contact.

A 0.145-kg baseball pitched horizontally at 37.9 m/s strikes a
bat and is popped straight up to a height of 54.0 m .
If the contact time is 1.90 ms , calculate the magnitude of the
average force on the ball during the contact.
Calculate the direction of the average force on the ball during
the contact.

A 0.135-kg baseball pitched horizontally at 30.5 m/s strikes a
bat and is popped straight up to a height of 36.5 m.
Part A:
If the contact time between bat and ball is 3.0 ms , calculate
the magnitude of the average force between the ball and bat during
contact.
Favg = ____ N
Part B:
Find the direction of the average force on the ball.
Theta = __ degrees

A bat strikes a 0.145-kg baseball. Just before impact, the ball
is traveling horizontally to the right at 55.0 m/s , and it leaves
the bat traveling to the left at an angle of 35 ? above horizontal
with a speed of 60.0 m/s . The ball and bat are in contact for 1.85
ms .
A. Find the horizontal component of the average force on the
ball. Take the x-direction to be positive to the right
Express your answer...

A bat strikes a 0.145-kg baseball. Just before impact, the ball is
traveling horizontally to the right at 49.0 m/s ; when it leaves
the bat, the ball is traveling to the left at an angle of 31.0 ∘
above horizontal with a speed of 54.0 m/s . The ball and bat are in
contact for 1.61 ms . Find the horizontal and vertical componenets
of the average force on the ball

A bat strikes a 0.145-kg baseball. Just before impact, the ball
is traveling horizontally to the right at 45.0 m/s , and it leaves
the bat traveling to the left at an angle of 35 ∘ above horizontal
with a speed of 65.0 m/s . The ball and bat are in contact for 1.65
ms .
A. Find the horizontal component of the average force on the
ball. Take the x-direction to be positive to the right
(two sig figs)...

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 pitched 200 g baseball, in the horizontal flight with a speed
of 120 km/h, is struck by a bat. After leaving the bat, the ball
travels in the opposite direction at an upward angle of 60.00 with
80 % of the original speed.
(a) What impulse (magnitude and direction) acts on the ball while
it is in contact with the bat during the collision?
(b) The impact time for the baseball-bat collision is 1.50 ms.
What is the magnitude...

A pitcher throws a 0.140-kg baseball with a speed of 28.9 m/s.
The batter strikes it with an average force of 5000 N which results
in the ball traveling with an initial speed of 37.0 m/s toward the
pitcher. For how long were the bat and ball in contact?
1.32 × 10-2 s
4.44 × 10-3 s
3.17 × 10-2 s
1.85 × 10-3 s
