$11\mathrm{.}112$ A model rocket is launched from point A with an initial velocity $v_0$ of $75\frac{m}{s}.$ If the rocket's descent parachute does not deploy and the rocket lands a distance $d=100m$ from $A,$ determine $(a)$ the angle $$ that $v_0$ forms with the vertical, $(b)$ the maximum height above point A reached by the rocket, $(c)$ the duration of the flight.
