# [Help] Physics - Forces watch

1. may someone help me on this question, i can't find the right formula

Question
Calculate Force exerted by the ground on the rocket

Information
Mass of the Rocket = 1500kg
Duration of landing impact = 0.04 s
Velocity at time of impact = 175 m/s
Distance travelled = 30km
Time taken to complete journey = 6 minutes
Acceleration due to gravity = 9.8 m/s^2

I know this is GCSE physics but i've forgotten the formula

Force=change of momentum/time during momentum change
3. Thanks i'll try it now
