A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration...
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?

A 2590-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 2.00 m/s2 and 1.60 s later an upward velocity of 2.46 m/s . At 4.30 s after...

12. The only rocket that has ever lifted humans beyond low Earth orbit was the Saturn V, which had three stages of propulsion. Fully fueled, the rocket plus its cargo had a mass of 2.97x10 kg. The first stage consumed fueltoxidizer at a rate of 1.5x10 kgs, and had an exhaust speed of 2.6x10*m/s. (a) Calculate the thrust that was produced by the first stage. (b) Determine the acceleration of the rocket just after lift-off from the launch pad. 3
