Question

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.

Answer #1

A ball with a mass of 0.615 kg is initially at rest. It is
struck by a second ball having a mass of 0.405 kg , initially
moving with a velocity of 0.275 m/s toward the right along the x
axis. After the collision, the 0.405 kg ball has a velocity of
0.215 m/s at an angle of 36.9 ? above the x axis in the first
quadrant. Both balls move on a frictionless, horizontal
surface.

A ball with a mass of 0.590 kg is initially at rest. It is
struck by a second ball having a mass of 0.390 kg , initially
moving with a velocity of 0.275 m/s toward the right along the x
axis. After the collision, the 0.390 kg ball has a velocity of
0.185 m/s at an angle of 37.8 ∘ above the x axis in the first
quadrant. Both balls move on a frictionless, horizontal
surface.

A ball with a mass of 1.1 kg is initially at rest. It is struck
by a second ball having a mass of 1.3 kg, initially moving with a
velocity of 3.5 m/s toward the right along the x axis. After the
collision, the 1.3 kg ball has a velocity of 2.7 m/s at an angle of
35? above the x axis in the first quadrant. Both balls move on a
frictionless, horizontal surface. Do not assume that the collision...

A ball with mass M = 5 kg is moving with speed V=10 m/s and
collides with another ball with mass m = 2.5 kg which is initially
stationary. There is no other force such as gravity acting on the
two balls. After the collision, both balls move at angle θ=30
degrees relative to initial direction of motion of the ball with
mass M = 5 kg. a) What are the speeds of the two balls after the
collision? b)...

A white billiard ball with mass mw = 1.47 kg is
moving directly to the right with a speed of v = 3.01 m/s and
collides elastically with a black billiard ball with the same mass
mb = 1.47 kg that is initially at rest. The two collide
elastically and the white ball ends up moving at an angle above the
horizontal of θw = 68° and the black ball ends up moving
at an angle below the horizontal of...

A white billiard ball with mass mw = 1.6 kg is moving
directly to the right with a speed of v = 2.98 m/s and collides
elastically with a black billiard ball with the same mass
mb = 1.6 kg that is initially at rest. The two collide
elastically and the white ball ends up moving at an angle above the
horizontal of θw = 48° and the black ball ends up moving
at an angle below the horizontal of...

a 1.5 kg car (1) initially moving at 4.0 m/s to the right
collides with a 2.0 kg car (2) initially moving at 2.0 m/s to the
left. After the inelastic collision, car 1 is moving to the left at
1.2 m/s
A) What is the velocity and direction of car 2 after the
collision?
B) What is the change in total kinetic energy and the percentage
of initial kinetic energy remaining after the collision?

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.
