Solve the all parts of given question:
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. The takeoff ramp was inclined at = 53.0 degrees, the river was = 36.0m wide, and the far bank was = 18.0m lower than the top of the ramp. The river itself was = 86.0m below the ramp. You can ignore air resistance.
Part A: 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?
Part B: If his speed was only half the value found in part A, where did he land?
