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)

A 0.155-kg glider is moving to the right on a frictionless,
horizontal air track with a speed of 0.81 m/s. It has a head-on
collision with a 0.310-kg glider that is moving to the left with a

magnitude
--- m/s
b. 0.310-kg glider magnitude---m/s

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)...
