Awwww come on. All the information you need is provided.

Force = mass x acceleration

Acceleration = rate of change of velocity

You are given the mass, initial and final velocity and the time taken to go from one to the other.

Work = force x distance moved.

Use a suitable SUVAT equation to calculate the distance travelled in 1.2 seconds.

Then it's a case of plugging the numbers.
