During fuel burn, the vertically launched Terrier-Sandhawk rocket had an acceleration of 300m/s^2 (about 30 times free-fall acceleration called 30g). The fuel burned for 8.0 s. Find the height of the Terrier-Sandhawk rocket at the end of fuel burn.

Potential energy and kinetic energy are created when work is done to change a position (PE) or a state of motion (KE). Ignoring friction, how does the amount of work done to make the change compare to the amount of PE or KE created? a.
