The impulse is given as 15000 Newton-seconds. you have incorrectly used this value as a force of 15000 Newtons.tani said:Homework Statement
Far in space, where gravity is negligible, a 495 kg rocket traveling at 85.0 m/s fires its engines. The impulse imparted to the rocket is 15000Ns, for 30 seconds. What is the maximum velocity of the rocket?
Homework Equations
F(delta t)=mv2-mv1
The Attempt at a Solution
v2=((15000*30)+(495*85))/495
v2=994m/s
Why isn't this answer correct?
Rocket momentum is a measure of the quantity of motion of a rocket, which is determined by its mass and velocity.
The momentum of a rocket can be calculated by multiplying its mass by its velocity. The formula is: momentum = mass x velocity.
The maximum velocity of a rocket is the highest speed it can reach during its flight.
The max velocity of a rocket can be calculated by using the formula: max velocity = square root of (2 x thrust x burn time) / (mass x drag coefficient x air density x rocket area).
The max velocity of a rocket can be affected by several factors including its mass, thrust, burn time, drag coefficient, air density, and rocket area. Changes in these variables can impact the overall momentum and speed of the rocket.
