(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...
