A test rocket is fired vertically upward from a well. A catapultgives it an initial speed of 81.0 m/s at ground level. Its enginesthen fire and it accelerates upward at 3.90 m/s^2 until it reachesan altitude of 930 m. At that point its engines fail, and therocket goes into free fall, with an acceleration of -9.80 m/s^2.(You will need to consider the motion while the engine is operatingseparate from the free-fall motion.)

a) How long is the rocket in motion above the ground? ______s
b)What is its maximum altitude? ______km
c) What is its velocity just before it collides with the Earth?_____m/s

A test rocket is fired vertically upward from a well. A catapultgives it an initial speed of 81.0 m/s at ground level. Its enginesthen fire and it accelerates upward at 4.10 m/s2 until it reachesan altitude of 940 m. At that point its engines fail, and therocket goes into free fall, with an acceleration of -9.80 m/s2.(You will need to consider the motion while the engine is operatingseparate from the free-fall motion.)
(a) How long is the rocket in motion above the ground?

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 39.2 m/s2. The acceleration period lasts for time 6.00s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2.
