During a curling competition a curler accelerates a 20.0 kg curling rock at a rate of 0.95 m/s squared down a low friction lane of ice. Determine the distance the curlers hand is in contact with the rock if 50.0 J of work was done on the rock by the curler during the release. (2.6m)

Use W=Fd to determine the distance d. You can calculate F from the mass and acceleration data: F=ma.
