A 1000kg rocket is moving forward at 10m/s in space. A 10,000N force is applied to the rocket for one second from behind. How fast is the rocket now traveling?

a. 0m/s
b. 10m/s
c. 15m/s
d. 20m/s

F = ma,
a = F / m = 10000 / 1000 = 10m/s^2,

V = Vo + at,
V = 10 + 10*1 = 20m/s.

Resultant force divided by mass
= 10000(force applied) +10000(f=m divided a) =20000 N
20000 N divided by mass 1000kg= 20m/s
