Question

what thrust is required to fire a 350 kg rocket with an acceleration of 8 m per second square.please answer with full steps.

Answer 1

The forces acting on the rocket are :
1. Thrust(in the upward direction)=$F_{thrust}$
2. Gravity(in the downward direction)=$F_{gravity}$
Hence, the net force acting on the rocket is:
$F_{net}= F_{thrust} -F_{gravity} \\ F_{thrust}=F_{net}+F_{gravity} \\ F_{thrust}=m a_{net}+mg=m(a_{net}+g) =350(8+10)=6300N$
