A 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 35 m/s2 for 31 s, then runs out of fuel. Ignore any air resistance effects. What is the rocket's maximum altitude? How long is the rocket in the air before hitting the ground? Express your answer with the appropriate units.

A small sounding rocket has an initial mass of M=3200kg (80% of which is fuel) and burns fuel at a rate of 20 kg/s. The exhaust velocity of the gas ejected from the rocket is Uex=2000m/s. a. Find the thrust of the rocket motor. b. Find the time until burnout. c. Find the speed of the rocket at burnout assuming that the rocket moves straight up and stays close enough to Earth's surface that the gravitational acceleration is always g=9.81m/s^2

A 170 kg rocket is moving radially outward from the earth at an altitude of 180 km above the surface with a velocity of 3.5 km/sec. At this point, its final stage engine shuts off. 1) Ignoring any minor air resistance, what is the rocket's velocity 780 km above the surface of the earth?"; m/sec 2) Again ignoring any minor air resistance, what is the rocket's velocity 780 km above the surface of the earth if its mass were 340...

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...

4: Suppose the mass of a
rocket just as it runs out of fuel is 75550-kg, and its exhaust
speed is 2.7 × 103 m/s.
Calculate
the maximum rate, in kilograms per second, at which the rocket can
expel gases, if its acceleration cannot exceed seven times that of
the gravitational acceleration on the surface of the Earth. Assume
the gravitational force on the rocket is negligible.

A rocket moves upward starting from rest with an acceleration of 20 m/s^2 for 5 s. It runs out of fuel at the end of this 5 s and continues to move upward, acted upon only by gravity. How high does it rise? Find the velocity of the rocket just before it hits the ground and how long it is in the air?
