A model rocket launches with an initial velocity of 7 m/s, at an angle of 81 degrees (with respect to the horizon). The rocket's engine provides an acceleration of 2.3 m/s^2, acting in the same direction as the initial velocity. After 18 seconds, the rocket engine cuts out.
a.) What is the maximum height attained by the rocket?
miles
b.) How far does the rocket travel in the horizontal direction?
feet
c.) What is the total flight time?
minutes
