2. A rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 m/s^2 and feels no air resistance. When it has reached a height of 525 m, its engines suddenly fail so that the only force acting on it is now gravity.

a) How fast is the rocket traveling when the engine fails? b)What is the maximum height the rocket will reach above the launch pad? c) How much time after engine failure will elapse before the rocket comes crashing down to the launch pad? d) What is the rocket's velocity just before it crashes into the earth?

A 25kg rocket stays on a launch pad at rest when it's engines fire and a constant thrust pushes the rocket upward with a constant 500N thrust force. The engines fire for the first 20 m and then abruptly cut off. The maximum height of the rocket is 35m. How much energy does air resistance take away from the rocket?

A 2400-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 1.90 m/s2 and 1.20 s later an upward velocity of 1.50 m/s . Part A) Determine A....

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 81.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 1020 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)...

Carlon launched a toy rocket vertically from ground level (y=0m, time=0s). The rocket's engine provides constant acceleration during the burn phase. At the instant of engine burnout the rocket has risen 89m. The rocket continues to rise in unpowered flight, reaches mex height of 232m, and then falls back to the ground. What is the rocket engine upward acceleration closest too? A. 12.1m/s B. 22.3 m/s C 15.8 m/s

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.10 m/s2 . When it is 235 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored). How high is the rocket when the canister hits the launch pad, assuming that the rocket does...
