1. A bottle rocket has an engine that accelerates it upward. Then it coasts to its highest point before returning to the ground. Assuming that the engine creates a net acceleration of 30 m/s2 for 0.5 s, how high does it go, and how long does it take to reach the ground again?
The Attempt at a Solution
to get total height i did 11.48m+3.75m=15.23m
now how do i get velocity for the other question
does this work?
