Question

A 0.1kg steel ball moving at 4m/s to the right elastically collides with a 0.4kg steel ball moving to the right at 1m/s. What are the speeds/directions of each ball after the collision?

Answer #1

A steel ball of mass 200g moving with a velocity of 10 m/s
collides elastically with another ball of same mass at rest, then
calculate the followings. (your answer must be in SI units) (4
points)
a. Total momentum of the system before collision =
b. Total Kinetic energy of the system before collision =
c. Total momentum of the system after collision =
d. Total Kinetic energy of the system after collision

A
.06 kg tennis ball, moving at 2.50 m/s collides with a .09 kg ball
moving away from it at 1.15 m/s. Assuming a perfectly elastic
collision, what are the speeds and directions of the balls after
the collision?
Please explain each step or why you do what you do!

A 2.5 g steel ball moving 0.40 m/s collides elastically with a
stationary, identical ball. As a result, the incident ball is
deflected 30.0 degrees from its initial path (remember the 90
degree rule for same masses). 1. Draw a vector diagram showing the
momentum of each ball after the collision 2. What is the velocity
of the incident ball after the collision? 3. What is the velocity
of the struck ball after the collision?

A 25 g object moving to the right at 20 cm/s overtakes and
collides elastically with a 10 g object moving in the same
direction at 15 cm/s. Find the velocity of each object after the
collision.

A 27.0 g object moving to the right at 16.0 cm/s overtakes and
collides elastically with a 5.0 g object moving in the same
direction at 15.0 cm/s. Find the velocity of each object after the
collision.

A 26.0-g object moving to the right at 19.5 cm/s overtakes and
collides elastically with a 11.0-g object moving in the same
direction at 15.0 cm/s. Find the velocity of each object after the
collision. (Take the positive direction to be to the right.
Indicate the direction with the sign of your answer.)

A 110 g ball moving to the right at 4.0 m/s catches up and
collides with a 410 g ball that is moving to the right at 1.0 m/s
.
If the collision is perfectly elastic, what is the speed of the
110 g ball after the collision?
If the collision is perfectly elastic, what is the direction of
motion of the 110 g ball after the collision?
If the collision is perfectly elastic, what is the speed of the...

A ball of mass 0.305kg that is moving with a speed of 5.7m/s
collides head-on and elastically with another ball initially at
rest. Immediately after the collision, the incoming ball bounces
backward with a speed of 3.3m/s.
Calculate the velocity of the target ball after the
collision.
Calculate the mass of the target ball.

A
0.10 kg ball A moves to the right at 0.35 m/s and collides
elastically and perfectly head on with the 0.30 kg ball B that
moves to the rigth at 0.050 m/s. The velocity of ball A after the
callision is?

A ball of mass 0.250 kg that is moving with a speed of 5.5 m/s
collides head-on and elastically with another ball initially at
rest. Immediately after the collision, the incoming ball bounces
backward with a speed of 3.1 m/s . Calculate the velocity of the
target ball after the collision. Calculate the mass of the target
ball.
