A daredevil tries to jump a canyon of width 15 m. To do so, his motorcycle up an incline slope at an angle of 22 degrees. What minimum initial velocity is necessary to clear the canyon?

Answer 1

it will take 15/(v cos22°) seconds to cross the gap.
It will take half that time to reach the top of the parabola, so find when
the vertical speed is v sin22° - 9.8t = 0

Answer 2

Superman can “leap tall buildings in a single bound.” Assuming the man of steel starts and stops on the ground, how high a building could superman jump over if you want to leave the ground at the speed of 82.0 m/sec at a 75° launch angle.
