this is vectors and projectiles...our teacher told us how to do it...and i did exactly what he told us to do, but it isn't right...
A rocket is launched at an angle of 53° above the horizontal with an initial speed of 75 m/s, as shown in Figure 3-31. It moves for 21 s along its initial line of motion with an acceleration of 21 m/s2. At this time its engines fail and the rocket proceeds to move as a free body.
(a) What is the rocket's maximum altitude?
(b) What is the rocket's total time of flight?
(c) What is the rocket's horizontal range?
