Question

A 2.00-kg ball is moving at 4.80 m/s toward the right. It collides elastically with a 4.00-kg ball that is initially at rest.

1. Calculate the final velocity of the 2.00-kg ball.
*(Express your answer to three significant figures.)*

*2.* Calculate the final velocity of the 4.00-kg ball.
*(Express your answer to three significant figures.)*

Answer #1

A 4.80-kg ball, moving to the right at a velocity of +1.26 m/s
on a frictionless table, collides head-on with a stationary 8.20-kg
ball. Find the final velocities of (a) the 4.80-kg
ball and of (b) the 8.20-kg ball if the collision
is elastic. (c)Find the magnitude and direction of
the final velocity of the two balls if the collision is completely
inelastic.

A 4.80-kg ball, moving to the right at a velocity of +3.36 m/s
on a frictionless table, collides head-on with a stationary 6.10-kg
ball. Find the final velocities of (a) the 4.80-kg ball and of (b)
the 6.10-kg ball if the collision is elastic. (c) Find the
magnitude and direction of the final velocity of the two balls if
the collision is completely inelastic. (a) Number Units

A 4.80-kg ball, moving to the right at a velocity of +1.70 m/s
on a frictionless table, collides head-on with a stationary 7.75-kg
ball. Find the final velocities of the balls if the collision meet
the following conditions.
(a) elastic
4.8-kg ball
=_________ m/s
7.75-kg ball
=_________ m/s
(b) completely inelastic _________m/s

A ball of mass 0.310 kg that is moving with a speed of 5.7 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 .
1. Calculate the velocity of the target ball after the
collision.
2. Calculate the mass of the target ball.

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.

A ball of mass 0.265 kg that is moving with a speed of 5.1 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 3.5 m/s .
Part A: Calculate the velocity of the target ball after the
collision.
Part B: 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 3.20-kg object is moving east at 4.50 m/s when it collides
with a 6.00-kg object that is initially at rest. After the
completely elastic collision, the larger object moves east at 3.13
m/s.
1) What is the final velocity of the smaller object after the
collision? Assume that the positive direction is to the
east.(Express your answer to three significant figures.)

A ball with a mass of 2 kg is initially moving to the right with
a speed of 3 m/s. It collides with a 5 kg ball moving to the left
with a speed of 1 m/s. The balls collide partially elastically: 70%
of the initial kinetic energy of the system is conserved in the
collision. Find the final velocity of each ball. The balls move
only along the x-axis. Show your work.

A 5.0 kg red ball moving to the east at 9.0 m/s collides
elastically head-on with a 10.0 kg green ball moving to the west at
3.0 m/s. What are the final velocities of both balls?
