Question

Engineers at the caramel space institution must determine the net force needed for a rocket achieve an acceleration of 90m m/s/s. if the mass   of the rocket is 35,000kg, how much net force must be the rocket

 develop? 

Answer 1

Given:

$a=90\:\rm m/s^2$

$m=35\: 000\:\rm kg$

The Newton's second law says

$$F=ma\\ =35\:000\:\rm kg*90*\: m/s^2=3\:150\:000\: N$$
