A model rocket is launched straight upward with an initial

speed of 50.0 m/s. It accelerates with a constant upward

acceleration of 2.00 m/s^{2} until its engines stop at an altitude

of 150. m. (a) What can you say about the motion of the

rocket after its engines stop? (b) What is the maximum height

reached by the rocket? (c) How long after liftoff does the

rocket reach its maximum height? (d) How long is the rocket

in the air?

Step 1

(a) write the expression for final velocity when the engine stops

Step 2

Substitute the values

Step 3
