here's the question...ill make it short a guy wants to leap a river. THe takeoff ramp is inclined at 53 degrees. The river is 40m wide, and the far bank where he is gonna land is 15m below the top of the take off ramp. The river itself is 100 m below the ramp. Ignoring air resistence, find initial velocity. ok so...the Y i would use for this is simple..85m (100m-15m). But..i cant use the quadratic formula to find t, and i have two unknowns since V is not given either. so far the equations ive used ive had 2 unknowns, so...I need a hint or anything to get me in the right directions. Thanks.
