Carlon launched a toy rocket vertically up from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration of 12.3 m/s2 during the burn phase. At the instant of engine burnout the rocket has risen to 89 m. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:

Student Activity 9 A 30 kg rocket toy lifts off vertically from the ground. After 3 minutes, its engine stops. The rocket has then a speed of 320 m/s and is at an altitude of 2600 m. a) What is the work done by the rocket engine? b) What is the average power of the rocket engine? (Actually, the mass of the rocket decreases as fuel is ejected, but we will proceed as if the mass remains constant.)

6) Some time, At, after a rocket blasts off from the surface of Earth, it is travelling at a constant speed, and its instantaneous mass (including fuel) is M 20,000 kg. The gas ejected out the back of the rocket is moving at a relative velocity of 1,200 m/s (downward) with respect to the rocket. You may assume that the rocket is still very close to the surface of the Earth, and that air resistance is negligible. A) What is...

Why
is the answer B?
13) A toy rocket is launched vertically from ground level (y 0 m), at timet- 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 72 m and acquired a velocity of 40 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:...
