a) I would multiply 1.81x10^5*480

b) Would I used the answer from a) and divide by acceleration?

c)i am not sure what to do for this part

Thrust=mv/t= m/t *v You are given the fuel burn rate (m/t) and v.

massleft= intial mass - fuelburnrate*time

Speed of rocket= thrust*timeburn/avgmassrocket

where average mass of rocket= starting mass -fuelburned/2
