Question

Mass m 1=m 2. Mass m 1 is moving at 5m/s. A second mass m 2 is stationary. m 1 hits m 2. The collision was elastic and there is no friction. Was is the velocity of m 1 after the collision?

Answer #1

A ball of mass 2 kg is moving with a velocity of 12 m/s collides
with a stationary ball of mass 6 kg and comes to rest. calculate
the velocity of the 6 kg ball after the collision. (both balls are
elastic)

An object of mass m1=6.1 kg moving at 5.1 m/s strikes a
stationary second object of unknown mass. After an elastic
collision, the first object is observed moving at 3.06 m/s at an
angle of -43° with respect to the original line of motion. What is
the energy of the second object?

1. A horizontal moving walkway is moving at 3 m/s. On the
average, during each second, four stationary people step onto it
and four people step off it. Assuming each person’s mass is 60 kg,
what average driving force must be exerted on the walkway to keep
it moving? (Ans: 720 N)

A 62 kg ice skater moving at 3.2 m/s collides with a second
stationary skater with mass 65 kg. The skaters cling together after
the collision and move without friction. Compute their speed after
the collision.

1. A mass ma=2m, with an initial
velocity of 4 m/s, and a mass mb=m,
initially at rest, undergo an elastic collision. Calculate their
final velocities after the collision.
2. A mass ma=2m, with an initial
velocity of 4 m/s, and a mass mb=m,
initially at rest, undergo a perfectly inelastic collision.
Calculate the final velocity after the collision and the
kinetic-energy loss.
3. A moving mass,m1, collides perfectly
inelastically with a stationary mass,m2. Show

2. A 0.768 kg object is moving with a velocity of
2.53 m/s. A 0.532 kg moving object
hits it. After
collision, the 0.768 kg object has a velocity of 3.22 m/s and the
0.532 kg
object has a velocity of 0.636
m/s. What was the velocity of the 0.532 kg object
before collision? (All
motion is 1-D; friction can be ignored.)

A glider of mass m1 = 8 kg has a velocity
v1i = +2 m/s before colliding
with a second glider of mass m2 = 4 kg, moving
with velocity v2i = -4 m/s.
After the collision the first glider has a velocity of
v1f = -1 m/s. This collision
is
Elastic
Partially inelastic
Totally inelastic
Impossible
