A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.4 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2until it reaches an altitude of 1090 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.)
(a) For what time interval is the rocket in motion above the
ground?
(b) What is its maximum altitude?
(c) What is its velocity just before it hits the ground?

A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration of 2.60 m/s2 .At 30.0 s after blastoff, the engines suddenly fail, and the rocket begins free fall. What is the height of the rocket when the engine fails? Find the magnitudes of the rocket's velocity and acceleration at its highest point. How long after it was launched will the rocket fall back to the launch pad?

(8%) Problem 11: A student launches a small rocket which starts from rest at ground level. At a height of h- 1.85 km the rocket reaches a speed of ve 395 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem.
