A space shuttle has a mass of 2.5 x 10^6 kg. At lift-off the engines generate an upward force of 30 x 10^6 N. What's the weight of the shuttle in newtons? What's the acceleration of the shuttle when launched in m/s^2? The average acceleration of the shuttle during its 10 minute launch is 14 m/s2. What velocity does it attain in km/s?

The weight of the shuttle is mg.
The acceleration of the shuttle is computed from ma = T - mg where T is the thrust from the engines and mg is the weight of the shuttle.
The final question is simple kinematics;
v = vo + at
vo is zero, a is 14 m/s^2, t is 10 minutes (600 seconds), solve for v.
