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 rest from the top of a
building of height h. At
the same instant, a second ball is projected vertically upward from
ground level, such that it has zero speed when it reaches the top
of the building.
a) When do the two balls pass each other?
Answer it in terms of h.
b)Which ball has greater speed when they are
passing?
c)What is the height of the two balls when they
are passing?
If dropped
together from a height h,
how high does a tennis ball on top of a basketball bounce (tennis
ball’s mass is much smaller than basketball’s mass) ?
(please explain this in steps with very in depth explaination,
i am dumb lol please explain like you are explaining to a little
kid. do not write in cursive)
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.
