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