Asked by arriell
a rocket that has consumed all of its fuel continues to move upward slowed mostly by the force of gravity. If the rocket's mass is 75.0 g and it takes 1.2 sec for the rocket to stop, what is the change in the rocket's momentum?
what is the rockets stopping distance?

Assuming the value of g is 9.8m/s^2
Force*time=momentum
mass*g*time=momentum
be certain to change mass to kg.
velocity= momentum/mass
distance= velocity^time- g/2 *time^2
