Question

Force on a body () is given by =



, where is the momentum of the given body and is the time taken.

Momentum is given by = , where is the mass of the body and is the velocity of the body. Now,

consider a rocket which loses mass as it gains velocity over time. Given that the mass of the rocket varies with

time as given by =

2000

+5

and the speed of the rocket varies with time given by = 10

3−1.The magnitude

of force on the rocket at time = 20 is​

Answer 1
