Question

A steel ball with mass 40.0 g is dropped from a height of 2.00 m onto a horizontal steel slab. The ball rebounds to a height of 1.60 m.

(a) Calculate the impulse delivered to the ball during impact,
in N-m. *Define upward as positive.*

(b) If the ball is in contact with the slab for 2.00 ms, find
the average force on the ball during impact, in N. *Define
upward as positive.*

Answer #1

A 20 g ball is dropped from a height of 1.8 m. It rebounds from
the ground with 80% of the speed it had just before it hit the
ground. Assume that during the bounce the gound causes a constant
force on the ball for 75 ms. What is the force applied to the ball
by the ground in N?

A 160 g ball is dropped from a height of 2.2 m , bounces on a
hard floor, and rebounds to a height of 1.1 m . The figure(Figure
1) shows the impulse received from the floor.
Part A
What maximum force does the floor exert on the ball?

A ball falls from height of 20.0 m, hits the floor, and rebounds
vertically upward to height of 15.5 m. Assume that
mball = 0.335 kg.
(a) What is the impulse (in kg · m/s) delivered to the ball by
the floor?
b) If the ball is in contact with the floor for 0.0400 seconds,
what is the average force (in N) the floor exerts on the ball?

A ball with a mass of 2.0 kg is dropped from a height of 1.5 m.
The ball hits the floor and bounces back to a height of 1.1 m. Use
energy conservation wherever possible to answer these questions.
(a) What is the speed of the ball just before it reaches the floor
initially? (b) What is the speed of the ball just after it leaves
the floor? (c) How much work is done by the floor? (d) The
coefficient...

After dropping from a height of 1.50m onto a concrete floor, a
50g ball rebounds to a height of .90m. A. Find the impulse acting
on the ball as it dropped. B. Find the impulse acting on the ball
as it rebounds. C. Find the impulse on the ball while it was in
contact with the floor. Please show all calculations and steps
clearly.

After falling from rest from a height of 33 m, a 0.60-kg ball
rebounds upward, reaching a height of 23 m. If the contact between
ball and ground lasted 2.3 ms, what average force was exerted on
the ball? (Enter the magnitude.)
N

a
ball of mass 0.175kg is dropped from rest from a height of 1.25m.
it rebounds from the floor to reach a height of 0.825m. what
impulse was given to the ball by the floor? magnitude______
kg

After falling from rest from a height of 27 m, a 0.46 kg ball
rebounds upward, reaching a height of 17 m. If the contact between
ball and ground lasted 2.1 ms, what average force was exerted on
the ball?

1.
a tennis ball is dropped from a height of 2 m and it rebounds 95
cm. use g=10 m/s^2, and the tennis ball weights .058 kg.
a) find the change of momentum when the ball is at a height of
1.5 m downward and at 0.5 m downward. which i got -3.14 kg m/s for
the 1.5 m, and -0.18 kg m/s, and then what is the impulse exerted
on the object during that change of momentum?
b) compute...

A
ball of mass 2.25 kg is released from rest at height 5.29 m above
the floor. It falls, hits the ground, and rebounds to height 3.19 m
above the floor. Assume none of the losses are due to air friction.
Find the impulse, in N-s, exerted by the floor on the ball. The
sign of your answer will give the direction of the impulse.
