A model rocket with a mass of 500 grams is launched straight up. It achieves a speed of 20.0 m/s in 2.00 seconds. Ignoring any change in mass of the rocket due to expelled fuel, and neglecting air resistance, the average thrust force of the engines on the rocket is
Question 3 On 21 January 2018, Rocket Lab launched a 10 500 kg rocket from the Mahia Penin- sula. It carried a 250 kg payload that included the 8 kg Humanity Star, which is like a large disco ball in size and shape. (a) On the launchpad, the rocket has a mass of 10 500 kg and produces 160 kN of vertical thrust. Assuming that the acceleration is constant and motion is in a straight line, find the speed of...

A rocket, with an original mass of 20,000 kg, is launched vertically and expels 1000kg of mass every 20 seconds (take the average rocket recoil mass in applying momentum conservation). Determine the numerical value of the velocity of the rocket, after 2 10 second intervals, and also determine how far it has traveled at the end of that time.
A 1000 kg weather rocket is launched straight up.The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 6200 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16s? What is the rocket's speed as it passes through acloud 6200 m above the ground?
A rocket is launched upward from the surface of the earth with a thrust of 10,000 newton for 10 seconds. Other than gravity, no other forces act on the rocket. After the thrust is completed (so it is no longer exerting an upward force on the rocket) what is its acceleration?
A 150 kg rocket is launched at a 40 degree angle. The engine provides a force of 2000 newtons. The coefficient of kinetic friction is 0.2. The end of the ramp is 5 m high. What is the average operating power rating of the engine? What is the engine's power output the instant it leaves the ramp?
