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 0.03 m, at an angle 5 degrees (relative to the horizontal). The top of the ski jump is 317 m high off the ground. Block A of mass 23kg is released from the top of the slope so that it slides down and makes a perfectly elastic collision with Block B of mass 14.95kg. This causes the Block B to slide up the frictionless ramp and undergo projectile motion, before landing a horizontal distance x m away from the ramp. Part 1 What is the speed of Block B (in m/s), immediately after the perfectly elastic collision? Part 2 What is the horizontal distance (in m) that Block B travels after it goes off the ramp (x)?
