Suppose a rocket-propelled motorcycle is fired from rest horizontally across a canyon 1.00 km wide.(a) What minimum constant acceleration in the x-direction must be provided by the engines so the cycle crosses safely ifthe opposite side is 0.750 km lower than the starting point? (b) At what speed does the motorcycle land if it maintains thisconstant horizontal component of acceleration? Neglect air drag, but remember that gravity is .still acting in the negativey-direction
