Question

Ball A (0.500 kg) is tied to string like a pendulum and pulled to an

initial height. It is released from rest and collides wit

h Ball B (0.650 kg) at the lowest part of its swing. The collision is perfectly elastic.

After the collision Ball B has a speed 3.33 m/s.

A) With what velocity did Ball A strike Ball B?

B) What was the initial height of Ball A?

C) After the collision, what is the maximum height Ball A will reach?

Answer #1

A 148 g ball is tied to a string. It is pulled to an angle of
7.2 ∘ and released to swing as a pendulum. A student with a
stopwatch finds that 22 oscillations take 20 s .

A pendulum is made by tying a 0.50 kg ball to a 0.75 m long
string. It is pulled back to an angle of 35 degrees from the
vertical, and then released from rest.
(a) determine the change in the gravitational potential energy
between the moment it is released and the moment it reaches the
bottom of its swing. (The anwser is -0.665J)
(b) Determine the speed when it is at the bottom of the swing.
(the answer is 1.63...

A pendulum consists of a 5.2 kg ball suspended by a 1.3 m length
of string with negligible mass and is initially at rest. A 4.4 g
bullet travelling at 680 m/s is fired horizontally into the ball
and is lodged there. The ball and bullet rise together to a maximum
height of h. How long does it take from the moment of impact for
the ball to first reach its maximum height?

A ball of mass 0.484 kg moving east (+xdirection) with
a speed of 3.76 m/s collides head-on with a 0.242 kg ball at rest.
Assume that the collision is perfectly elastic.
A)What is be the speed of the 0.484-kg ball after
the collision? B)What is be the direction of the velocity of the
0.484-kg ball after the collision? C)What is the speed of the
0.242-kg ball after the collision? D)What is the direction of the
velocity of 0.242-kg ball after...

Starting with an initial speed of 4.36 m/s at a height of 0.100
m, a 1.74-kg ball swings downward and strikes a 5.65-kg ball that
is at rest, as the drawing shows. (a) Using the principle of
conservation of mechanical energy, find the speed of the 1.74-kg
ball just before impact. (b) Assuming that the collision is
elastic, find the velocity (magnitude and direction) of the 1.74-kg
ball just after the collision. (c) Assuming that the collision is
elastic, find...

Starting with an initial speed of 3.77 m/s at a height of 0.126
m, a 1.25-kg ball swings downward and strikes a 5.95-kg ball that
is at rest, as the drawing shows. (a) Using the principle of
conservation of mechanical energy, find the speed of the 1.25-kg
ball just before impact. (b) Assuming that the collision is
elastic, find the velocity (magnitude and direction) of the 1.25-kg
ball just after the collision. (c) Assuming that the collision is
elastic, find...

Starting with an initial speed of 4.49 m/s at a height of 0.148
m, a 2.76-kg ball swings downward and strikes a 5.25-kg ball that
is at rest, as the drawing shows. (a) Using the principle of
conservation of mechanical energy, find the speed of the 2.76-kg
ball just before impact. (b) Assuming that the collision is
elastic, find the velocity (magnitude and direction) of the 2.76-kg
ball just after the collision. (c) Assuming that the collision is
elastic, find...

A ball of mass 0.440 kg moving east (+x direction) with a speed
of 3.60 m/s collides head-on with a 0.260 kg ball at rest. If the
collision is perfectly elastic, what will be the speed and
direction of each ball after the collision?

A simple pendulum is made from a 0.760-m-long string and a small
ball attached to its free end. The ball is pulled to one side
through a small angle and then released from rest. After the ball
is released, how much time elapses before it attains its greatest
speed?

A simple pendulum is made from a 0.614-m-long string and a small
ball attached to its free end. The ball is pulled to one side
through a small angle and then released from rest. After the ball
is released, how much time elapses before it attains its greatest
speed?
