Two frictionless carts collide and stick together in a perfectly
inelastic collision, due to a magnetic or mechanical coupling, on a
one-dimensional track. Cart 1 has mass 200 grams and an initial
velocity of 2 m/s. Cart 2 has mass 900 g, and is initially
stationary. What is the velocity of the two carts together after
the collision?

Two objects collide in a totally inelastic collision. Just
before the collision,
the objects have the following masses and velocities:
M1 = 4.5 kg, v1 = 1.5 m/s @ 140o. M2 = 1.5 kg, v2 = 1 m/s @
180o.
a) Find the velocity of the object after the collision.
b) How much kinetic energy was lost in the collision.

Two ice skaters, Daniel (mass 69.0 kg) and Rebecca (mass 51.0
kg) are practicing. Daniel stops to tie his shoelace and, while at
rest, is struck by Rebecca, who is moving at 13.5 m/s before she
collides with him. After the collision, Rebecca has a velocity of
magnitude 6.3 m/s at an angle of 51.5° from her initial direction.
Both skaters move on the frictionless, horizontal surface of the
rink.

collides with him. After the collision, Rebecca has a velocity of
magnitude 8.00 m/s at an angle of 55.1 ∘ from her initial
direction. Both skaters move on the frictionless, horizontal

Two masses collide in an elastic collision,
with the following initial values:
m1 = 2 kg
m2 = 3 kg
v01 = 5 m/s
v02 = -4 m/s
Use the conservation rules, and algebra, what is the final
velocity of mass 1, vf1 in m/s?

Two ice skaters, Daniel (mass 65.0 kg ) and Rebecca (mass 45.0

at rest, is struck by Rebecca, who is moving at 12.0 m/s before she
collides with him. After the collision, Rebecca has a velocity of
magnitude 8.00 m/s at an angle of 54.1 ∘ from her initial
direction. Both skaters move on the frictionless, horizontal
