A 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 33 m/s2 for 31 s , then runs out of fuel. Ignore any air resistance effects.

What is the rocket's maximum altitude? Express your answer to two significant figures and include the appropriate units.

How long is the rocket in the air before hitting the ground? Express your answer to two significant figures and include the appropriate units.

A model rocket is fired straight up from the top of a 55-m-tall building. The rocket has only enough fuel to burn for 3.0 s. But while the rocket engine is burning fuel, it produces an upward acceleration of 60 m/s2. After the fuel supply is exhausted, the rocket is in free fall and just misses the edge of the building as it falls back to the ground. Ignoring air resistance, calculate 1. Determine the height above the ground of...

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 34.3 m/s2 . The acceleration period lasts for time 8.00 s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 .

A 1400 kg weather rocket accelerates upward at 10m/s2. It explodes 1.5 s after liftoff and breaks into two fragments, one twice as massive as the other. Photos reveal that the lighter fragment traveled straight up and reached a maximum height of 500 m . What was the speed of the heavier fragment just after the explosion? Express your answer using two significant figures.

You launch a model rocket from ground level. It moves directly upward with a constant acceleration of 73.0 m/s2 for 1.35 seconds, at which point it runs out of fuel. Assuming air resistance on the rocket is negligible, what is the maximum altitude (above the ground) achieved by the rocket? m

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 kids rocket is fired from rest from the ground (y=0) at time t1=0s. As the rocket fuel is burning its fuel it moves vertically upward with constant acceleation of +4.25m/s2. At t2=12s all fuel is used up and rocket is in freefall and air resistance can be neglected in this case. what is the maximum height of rocket with respect to ground? Also how long after being launched does the rocket return to the ground? And what is the...
