How much work was done on the mass?

1. Homework Statement
A 1.20 x10^3-kg block starting from rest is accelerated by a 2.20x10^3-N force for a distance of 50.0 meters along a horizontal frictionless surface.

a. What is the final velocity of the mass?

b. How much work was done on the mass?

I have no clue how to get A but for B i just Used W=Fd and got 2.20x10^3-N * 50m =
0.11 (Nm)

Can someone confirm my answer to B and help me with A?

Thanks.

Correct formula, but redo that arithmetic. (Keep better track of the exponents.)

For A, either find the acceleration and use kinematics or use the result of part B and relate the work done to the kinetic energy.
