Question

A baseball of mass 0.145 kg is thrown at a speed of 40.0 m/s. The batter strikes the ball with a force of 29,000 N; the bat and ball are in contact for 0.500 ms. The force is exactly opposite to the original direction of the ball.

1)

Determine the final speed of the ball.

Answer #1

A baseball approaching a batter with a speed of 25 m/s is hit
and leaves the bat in the directly opposite direction with a speed
of 50 m/s. The mass of the baseball is 0.15 kg.
a) What is the magnitude of the impulse (in N · s) exerted by
the bat on the baseball?
b) If the time of contact between the bat and the baseball is
2.9 ms, what is the average force exerted by the bat on...

Baseball: a baseball b, weighing .14 kg is thrown at 44 m/s at
the batter. The batter swings the bat B, which weighs 0.95 kg at 39
m/s hitting the baseball. Assume precise conservation of energy and
momentum and the motion during the hit is exactly horizontal.
Calculate the conservation of energy and momentum and solve for the
final velocities of the ball and bat. What is the total mechanical
kinetic energy? If the impulse is rectangular (goes to maximum...

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 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

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).

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 268 g baseball is thrown toward home plate at 21.8 m/s, and
the batter hits it right back at the pitcher at 41.6 m/s. Find the
magnitude of the impulse, in N-s, supplied by the bat to the
ball.
A 238 g baseball is thrown toward home plate at 38.2 m/s, and
the batter hits it right back at the pitcher at 33.8 m/s. Assume
the force exerted by the bat is approximately constant, and has
magnitude 139 N....
