## Homework Statement

Josie and Charlotte push a 12-kg bag of playground sand for a sandbox on a frictionless, horizontal, wet polyvinyl surface with a constant, horizontal force for a distance of 6 m, starting from rest. If the final speed of the sand bag is 0.5 m/s, what is the magnitude of the force with which they pushed

## Homework Equations

F=MA

W=Fdelta(r)cos(theta)

## The Attempt at a Solution

since cos0= 1 I thought it was 36 because W/6=F so w/6=12(.5) so how is W not 36. I'm obnviously forgetting a crucial step but don't understand where. Any help would be great, Thanks a lot.
