A physics professor did daredevil stunts in his spare time. His last stunt was an attepmt to jump accross a river on a motorcycle. The takeoff ramp was inclined at 53 degrees, the river was 4 meters wide, and the far bank was 15 meters lower than the top of the ramp. The river itself was 100 meters below the ramp. Ignore air resistance.
a.) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank?
b.) If his speed was only half the value found in (a), where did he land?

tnx for the answer, but i can'y understand what you wrote.. you stopped at:
a)vcos53*t=4 , t=vsin53/g,v^2sin106/2g=4,v^2=...
is there a next to this? hope you can make me understand... i'm really having a hard time.. sigh...
