Suppose a rocket-propelled motorcycle is fired from rest horizontally across a canyon 1.30 km wide.
(a) What minimum constant acceleration in the x-direction must be provided by the engines so the cycle crosses safely if the opposite side is 0.760 km lower than the starting point?
m/s2
(b) At what speed does the motorcycle land if it maintains this constant horizontal component of acceleration? Neglect air drag, but remember that gravity is still acting in the negative y-direction.
m/s
