Question
A 50 kg cart rests on frictionless surface. A net force of 75 N acts on the carts over a distance of 2m. What maximum speed does the cart reach?
Work: I can figure that the acceleration is 1.5m/s/s, Vi= 0. I was thinking maybe if I found time through the kinematic equation d=Vixt + a/2 X T^2. Then divide the time by distance to get speed. I don't really know. Please Help, Thank you.

why don't you use energy
workin=final KE
75*2=1/2 m v^2
solve for v
workin=final KE
75*2=1/2 m v^2
solve for v
