If a golf ball were dropped from a significant height and the
force of Drag is modeled by Fd=0.0057*V-0.0106, where V is the
velocity in m/s the Fd is the force of drag in N. The mass of the
golf ball is 0.0455 Kg.
h. How high will the golf ball bounce after the 5th impact with
the concrete surface ignore drag force?
i. If drag was included for G and H what type of analysis
technique would be needed
When
a golf ball or basketball is dropped to the pavement, it bounces
backup. (i) Is a force needed to make it bounce back up? (ii) if
so, what exerts the force?
(b) Whiplash
sometimes results from an automobile accident when the
victim
A ball is dropped from a building of height 100m. At the same
time, another ball is then thrown vertically up from the ground
with a velocity V0. They meet each other at
the middle. What is the speed V0 of the ball thrown
vertically up?
a) 44.3m/s
b)9.8m/s
c) 31.3m/s
d)19.6 m/s
e) 98.0m/s
A stone is dropped into a river from a bridge at a height h
above the water. Another stone is thrown vertically down at a time
t after the first is dropped. Both stones strike the water at the
same time. What is the initial speed of the second stone? Give your
answer in terms of the given variables and g.
2) A ball is dropped from rest at the top of a high cliff. It
takes 10.00 seconds for the ball to reach the ground below. Find:
a) the height of the cliff, b) the velocity of the ball hitting the
ground below, c) the time it takes for the ball to fall half of the
cliff's height, and d) the velocity at this halfway point.
(Remember acceleration due to gravity is -9.800 m/s^2).
A rubber ball is dropped from a height of 30 feet, and on each
bounce it rebounds up 22% of its previous height. How far has the
ball traveled vertically at the moment when it hits the ground for
the 23rd time? Round your answer to two decimal places.
A steel ball with a mass of 0.600 kg is dropped from an initial
height of 2.80 m onto a metal plate. The steel ball bounces
multiple times and on each bounce it returns to 75% of its previous
maximum height.
A)What is the initial mechanical energy of the ball-Earth
system, just after the ball is released from its initial height?
Use the surface of the steel plate as the y = 0 reference point for
the gravitational potential energy....

When a ball is dropped from 2 m, it only has potential energy
initially. When it hits the ground all that energy is converted to
kinetic energy. Write a program that will calclate the position of
the ball (y) as a function of time. Calculate y when the ball is
always higher than 0.5 m. Note that every time the ball hits the
ground it loses 10% of the total energy. Plot y vs. t. The mass...
A ball of mass 0.120 kg is dropped from rest from a height of
1.25 m. It rebounds from the floor to reach a height of 0.600 m.
What impulse was given to the ball by the floor?
magnitude?
direction? upward or downward
