Question

A rocket propels itself with a force of 5000N. Its mass is 500kg. If they rocket stops propelling itself at the 2 minute mark, how long will it take for the rocket to touch the ground(starting from when the rocket lifts off)?

Answer 1

To determine the time it takes for the rocket to touch the ground, we need to know its initial velocity and the force of gravity acting on it. The formula for calculating the final velocity of an object under constant acceleration is:

vf = vi + at

where
vi = initial velocity (m/s)
a = acceleration (m/s^2)
t = time (s)

Since we don't know the initial velocity and we don't know the force of gravity acting on the rocket, we can't find the time it takes for the rocket to touch the ground.
