Question

A small block of mass 2.7 kg is released from rest at the top of the curved frictionless ramp shown. The block slides down the ramp and is moving with a speed of 13.9 m/s when it collides with a larger block (1.5 times the mass). (Use g=10m/s²). If the larger block moves to the right with a speed of 5.5 m/s immediately after the collision, find the velocity of the small block immediately after the collision.

Answer 1

If it is horizontal...

momentum is conserved
2.7*13.9=2.7*5.5+1.5*2.7*V
solve for V
