m₁ = 2 kg m₂ = 3kg
h = 50 cm
Mass 1 is released from rest from height hand
slides down a frictionless 30° slope then collides
with mass 2. The two masses then stick together
and move as a unit on the horizontal ground.
a. What is the speed of mass 1 at the bottom of the slope just before it hits mass 2?
b. Mass 2 is initially at rest at the bottom of the slope. Mass 1 now collides with mass 2. Find
the speed of the combined masses after the collision.
