A) Determine the momentum of the ball immediately before the collision with the ground. B) Determine the momentum of the ball immediately after the collision with the ground. C) Determine the average force exerted on the ball during the collision. Now let: m = 0.080 kg y1 = 3.0 m y2 = 2.0 m ?t = 0.005 s. D) Determine the numerical value of the impulse of the ground on the ball during the collision. E) Determine the numerical value of the change in the kinetic energy during the collision

Answer #1

A
ball is dropped from rest from the top of a 6.10 m-y’all building,
falls straight downward, collides inelasrically with the ground,
and bounces back. The call loses 10.0% of its kinetic energy every
time it collides with the ground. How many bounces can the ball
make and still reach a windowsill that is 2.44 m above the
ground?

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.

A Wilson volleyball falls vertically from the initial height of
2.1 m with no initial velocity to the floor and bounces vertically,
reaching the highest point 1.7 m from the floor as illustrated.
Take the origin of the potential energy of the ball to be that on
the floor. The mass of the ball is 0.120 kg.

floor?
2)What is the magnitude of the impulse on the ball from...

A ball with mass of 0.025 kg is thrown horizontally with
velocity of 1.5 m/s toward a wall in positive X direction. It
collides with the wall, then bounces back to the left with velocity
of 1.0 m. The Collison takes 0.015s.
What is the total initial momentum?
b) What is the total final momentum?
c)What is change in momentum?
d)What is the impulse?
e) What is the average force acting on the wall by the ball
during the collision?...

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 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 Ping-Pong ball moving East at a speed of 4 m/s collides with a
stationary bowling ball. The Ping-Pong ball bounces back to the
West, and the bowling ball moves very slowly to the East. Which
object experiences the greater magnitude impulse during the
collision?
A car hits another and the two bumpers lock together during the
collision. Is this an elastic or inelastic collision?
In a game of pool, the white cue ball hits the #5 ball and
stops,...

a
1.2 kg ball moving with a velocity of 8.0m/s collides head on with
a stationary ball and bounces back at a velocity or 4.0 m/s. If the
collision is perfectly elastic, calculate (a) the mass of the other
ball (b) the velocity of the other ball after the collision (c) the
momentum of each ball before and after the collision (d) the
kinetic energy of each ball before and after the collision
