A long jumper leaps at an angle of 35 degrees at 9 m/s. How far will she jump?

Answer 1

This is a pretty standard problem. You plug into the range formula which is in every textbook or you find time in the air (2v_y0/g) and find the range by multiplying horizontal velocity times the time in the air.

The range formula is R = (v₀²/g)sin(2θ₀)

I'll leave the plug-in to you.
