Question

(a)
A superball of mass 0.1kg is dropped from a height of 3 meters
above the floor. It then bounces up to a height of 2.6 meters. Find
the velocity of the ball the instant before it reaches ground
level. (Hint: use energy equations)

(b) Calculate the velocity the ball must have after the bounce
at the instant it leaves the ground the reach the height of 2.6
meters.

(c) Use these velocities to calculate the change i. momentum
of the ball.

Answer #1

Thank you

A 2.0kg rubber ball is dropped from a height of 1.0m above the
floor.
a. Using energy (not
equations of motion), what is the ball’s speed just before it hits
the floor?
b. If it then bounces back to a height of 0.70m, what is the
speed of the ball, just as it leaves the ground? Again, use energy
rather than equations of motion.
c. How much kinetic
energy is lost?

A 0.6 kg ball is dropped from a height, h, of 2 meters (at point
A). It hits the ground and bounces back up to a height of 1 meter
(at point B) on its first bounce. (3 pts each)
a. What is the total energy of the ball at A?
b. What is the total energy of the ball at B?
c. Why did the ball not bounce back up to its starting
height?

A 1.5 kg ball is dropped from a height of 3 m above the ground
and upon striking the ground bounces up to a height of 2 m.
Ignoring air resistance, find the time it takes the ball to bounce
up to a height of 2 m after it is dropped.

A rubber ball of mass m is dropped from a height h. If the ball
loses energy on each bounce so that its speed just after each
bounce is 90% of its speed just before each bounce, then Önd an
expression for the height the ball reaches after the 3rd bounce

A 2.0-kg ball is dropped from a height of 5.0 meters. It hits
the ground and bounces upward. If it reaches a height of only 3.2
m, determine the magnitude of the work done by non-conservative
forces in this situation.

A 2.33 kg ball is
dropped from a height of 3 m. The ball then bounces back
upward a distance of 2.2 m. How much energy was lost in the
collision with the ground?
50.2 J
18.3 J
68.5 J
118.7 J
A 2.33 kg ball is
dropped from a height of 3 m. The ball then bounces back
upward a distance of 2.2 m. How much momentum does the ball have
immediately after bouncing off the ground?
5.13 kg m/s
21.6...

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...

2. A ball is thrown straight upward from the window of a
building 40 meters above the ground with an initial velocity of 20
m/s. Calculate
a. The speed of the ball after 1.5 sec.
b. The time needed for ball to reach its maximum height.
c. The maximum height.
d. The time needed for the ball to return back to the same
window which was thrown
e. The time needed for the ball to reach the ground.
f. Final...

An 80 kg object is dropped from rest from a height of
25 meters above the ground. Use the concept of energy conservation
to find its speed when it is 10 meters above the ground. (Please
explain, very confuse)

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
