Question

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.

Answer #1

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

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 0.155-kg baseball pitched horizontally at 34.0 m/s strikes a
bat and is popped straight up to a height of 35.5 m .Find the
direction (degrees) 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 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 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 0.14 kg baseball moves horizontally with a speed of 34 m/s
toward a bat. After striking the bat the ball moves vertically
upward with 40% of its initial speed. Find the direction and
magnitude of the impulse delivered to the ball by the bat.
° (measured from the initial direction of the ball)
kg·m/s

A pitcher throws a 0.15 kg baseball so that it crosses home
plate horizontally with a speed of 15 m/s. The ball is hit straight
back at the pitcher with a final speed of 29 m/s. (Assume the
direction of the initial motion of the baseball to be positive.)
(a) What is the impulse delivered to the ball? kg·m/s (b) Find the
average force exerted by the bat on the ball if the two are in
contact for 2.0 ✕...
