We need to find out net force and then apply equation of motion
Answer will be 906m/s

A 500 kg rocket is launched with a force of 20,000N. What is the speed of...
A 500 kg rocket carrying 4000kg of fuel is to be launched vertically. The fuel is consumed at a steady rate of 5oKg/s calculate the leastb velocity of exaush gases if the rocket will just lift off the launching pad immediately after firing.
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 rocket has an initial speed of 80.0 m/s when it is launched. It accelerates upward at a rate of 4.00 m/s2. (a) When does the rocket reach a height of 1000 m? (b) What is the rocket’s speed at that time? (c) At this point, the used first stage of the rocket is disconnected from the rocket. After this, the only force acting on the first stage is gravity. What is the maximum height reached by the first stage?
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?
