A frictionless ski jump is designed such that at the bottom of the hill, there is a short flat section.

After the flat section, the slope continues into a ramp of vertical height m, at an angle degrees (relative to the horizontal).

The top of the ski jump is high off the ground.

Block A of mass kg is released from the top of the slope so that it slides down and makes a perfectly elastic collision with Block B of mass kg. This causes the Block B to slide up the frictionless ramp and undergo projectile motion, before landing a horizontal distance $$x$$ away from the ramp.

## Part 1#

What is the speed of Block B (in ), immediately after the perfectly elastic collision?

Please enter in a numeric value in m/s.

## Part 2#

What is the horizontal distance (in ) that Block B travels after it goes off the ramp ($$x$$)?
