(1) A ski jumper leaves a ski jump at a speed of 24 m/s at an angle of 30o. She ultimately lands 20 meters below where she left the jump. (a) What is her speed when she hits the ground? (b) What is her speed at the apex of her jump? (c) What is her speed at the height of 20m above the ground?
I found part a to be 31 m/s but now I'm stuck and do not know how to approach b and c. Please help :)

A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. 1. How...
