a rocket is shot upward. its motor burns for ten seconds giving an acceleration of 15m/s/s, but after it burns it is in free fall. draw the velocity v. time graph, acceleration v. time graph and the position v. time graph. how high above the ground is the rocket once the motor runs out, how fast is the rocket traveling once its motor runs out, how fast is the rocket traveling when it reaches its maximum height, and what is its maximum height ?
The height at which fuel burns out is
The velocity at the maximum height
The maximum height is

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.2 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.10 m/s2 until it reaches an altitude of 1190 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)...
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...

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 79.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.20 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2.

A model rocket accelerates from rest upwards at 50 m/s^2 for 2s before its engine burns out. The rocket then coasts upward. What is the maximum height that the rocket reaches (assume air resistance is negligible)?
4. A rocket was traveling straight upward at a constant velocity vo- 80 m/s before it runs out of fucl at a height h- 8000 m. The rocket then continues its vertical motion reaching its maximum height at point A, before turning down in a free fall motion back to ground. (Take g -10 m/s) (a) Determine the maximum height reached by the rocket with respect to O (b) How long - from O- does it take the rocket to...
Same question qith different parts f A model rocket is fired vertically upward from rest. Its acceleration for the first three seconds is atet) sat, at which time the fuel is exhausted and it becomes a nds later, the rocket's parachute opens, and the (downward) velocity slows inearty to-13 n/s in S s. The rocket then "hets" to the ground at that rate freely "Talling" body. Thirteer (a) Determine the position function s and the velocity function v (for all...
A model rocket blasts off from the ground, rising straight upward with a constant acceleration that has a magnitude of 82.0 m/s2 for 1.82 seconds, at which point its fuel abruptly runs out. Air resistance has no effect on its flight. What maximum altitude (above the ground) will the rocket reach?
A model rocket blasts off from the ground, rising straight upward with a constant acceleration that has a magnitude of 82.0 m/s2 for 1.70 seconds, at which point its fuel abruptly runs out. Air resistance has no effect on its flight. What maximum altitude (above the ground) will the rocket reach?
Problem 1, 15 points Arocket i lunched vertically from point Po(0), with the rocket motor providing thrust equivalent to an acceleration of 19.8 m/s2. After 3 seconds, the rocket reaches point P, and the rocket motor shuts down. For I second (up to a total flight time of 4 seconds), the rocket flies without thrust, while it rotates by 45o. Then, at point P2 the rocket motor is restarted, again providing thrust equivalent to an acceleration of 19.8 m/s? in...
