Suppose a rocket-propelled motorcycle is fired from resthorizontally across a canyon 1.20 km wide.
(a) What minimum constant acceleration in thex-direction must be provided by the engines so the cyclecrosses safely if the opposite side is 0.780 km lower than thestarting point?
m/s2
(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.
m/s
