Question

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

Answer #1

A rubber ball of mass 0.175 kg is released from rest from a
height of 1.25 m. It rebounds from the floor to reach a height of
0.630 m. What impulse was applied to the ball by the floor? (You
may safely ignore air resistance. Enter the magnitude in kg ·
m/s)

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.

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.

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 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...

A
ball of mass 5.93 kg is released from rest at height 7.62 m above
the floor. It falls, hits the ground, and rebounds to height 3.2 m
above the floor. Assume none of the losses are due to air friction.
Find the work done against friction, in J, on the ball during the
contact with the ground

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.

A ball with mass of 0.050 kg is dropped from a height
of h1 = 1 .5 m. It collides with the floor,
then bounces up to a height of h2 = 1.0 m. The Collison
takes 0.015 s.
Use part e to Calculate impulse ( J) ? Write the formula first
.
Use part f to Calculate the average force acting ( F) on the
ball by the floor during the collision?
*Write the formula
Calculate the change in the...
