A block of mass m₁ 2 kg moves at a velocity of v₁i = 2 m/s. It collides with another block of
mass m2 3 kg that is initially moving at a velocity of v₂i : 1 m/s. After the collision, the first
block is moving at a velocity of vif 1 m/s. Positive is in the +x direction.
(a) Find the speed of the second block after the collision.
