**1. Homework Statement**

A rocket moves upward, starting from rest with an acceleration of 29.4 m/s^2 for 4s. It runs out of fuel at the end of this 4s interval and continues to move upward.

a.) how high does it rise from the ground?

b.)When the rocket will hit the ground?

**3. The Attempt at a Solution**

lets say a>b is the 4s with fuel, the rocket would travel 235.2 meters in 4s

from b>c the initial velocity is 117.6 m/s so the rocket will continue for 705.6 m before peaking 12s

from c to the ground the final velocity is 135.79 m/s 13.8564s

a.) 940.8 meters

b.) 29.8564 seconds

Is this correct?
