**1. The problem statement, all variables and given/known data**

The mass of a space shuttle is approximately 2.0 x10^6 kg. If the thrust provides a force of 1.2 x 10^7 N, what is the acceleration of the space shuttle at lift off?

6.0 m/s2

0.06 m/s2

1.67 m/s2

0.167 m/s2

**2. Relevant equations**

Resultant force = thrust – weight

Acceleration = resultant force ÷ mass

**3. The attempt at a solution**

Weight: 2.0 x10^6 kg*9.8=19600000

Resultant Force: 1.2 x 10^7 N-19600000=-7600000

Acceleration: -7600000/2.0 x10^6 kg= -3.8 m/s^2

Not a choice and a negative acceleration
