Question

A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle. (See the figure.) The takeoff ramp was inclined at α = 50.0∘, the river was L = 38.0m wide, and the far bank was d = 19.0m lower than the top of the ramp. The river itself was H = 76.0m below the ramp. You can ignore air resistance.

Answer 1

What should his speed have been at the top of the ramp for him to have just made it to the edge of the far bank?
