A model rocket is fired straight up from the top of a
60-m-tall building. The rocket has only enough fuel
to burn for 3.0 s. But while the rocket engine is
burning fuel, it produces an upward acceleration of
60 m/s?. After the fuel supply is exhausted, the
rocket is in free fall and just misses the edge of the
building as it falls back to the ground. Ignoring air
resistance, calculate (a) the height above the
ground and the velocity of the rocket when its fuel
runs out; (b) the maximum height of the rocket; (c)
the time the rocket is in the air; and (d) the rocket's
velocity the moment before it hits the ground.
Correct answer is shown. Your answer 41.478 s was either rounded differently or used a
different number of significant figures than required for this part.
