Basically I understand to use: W = F x d to find out the work done, but where does the mass of the cart come into play?

Also, if the cart only goes 5m, how can I find the velocity?

Which kinematic equation will solve for velocity now that I know the mass, accel, but not time?

If you already have kinetic energy, you can solve q2 :

KE = function of speed and mass

Invert this to find the speed.

Kinetic Energy Gained = Work done

(assuming no heat losses)

1/2 mv^{2} = F.s

therefore v = sqr.rt { 2F.s/m}.
