# Frictionless Ski Jump Collision#

A ski jump consists of a hill, a short flat section, and a ramp. The hill has height of $${{ params.hill_h }}$$ $$\rm{m}$$ and the ramp has a height of $${{ params.ramp_h }}$$ $$\rm{m}$$, making an angle of $$\theta = {{ params.ramp_angle }}^\circ$$ with the horizontal.

Block A of mass $$m_A = {{ params_mA }}$$ $$\rm{kg}$$ is released from rest at the top of the frictionless hill and slides down to the frictionless short flat section, where it undergoes a perfectly elastic collision with Block B of mass $$m_B = {{params_mB }}$$ $$\rm{kg}$$. This causes Block B to slide up the frictionless ramp and undergo projectile motion, before landing a horizontal distance $$x$$ away from the ramp at the same height as the short flat section.

## Part 1#

What is the speed of Block B immediately after the perfectly elastic collision?

Please enter in a numeric value in $$\rm{m/s}$$.

## Part 2#

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

Please enter in a numeric value in $$\rm{m}$$.
