Question

A rocket is launched from the origin with an acceleration of 20.0 m/s2 at an angle of 30.0 degrees above the horizontal. The launch acceleration lasts for 2.00 seconds at which time the fuel is exhausted. The rocket then falls with an acceleration of 9.80 m/s2 downward. What is the time it takes to reach maximum height?

Answer 1

Approx 10m

Answer 2

using the fromula max height = u^2 sin^2theta/2g
