a force of 500 N on an object of 2 kg displaces it by 3 m. find the work done by the force and the objects final speed assuming it was initially at rest. GIVEN: F = 500 N m = 2 kg d = 3 m FORMULA: W = Fd where: W = Work, J, kg•m•m/s•s F = Force, N, kg•m/s•s d = distance, m EQUATION: W = Fd F = ma SOLUTION: W = Fd W = (500 N)(3 m) W = (500 )(3 m) W = 1500 W = 1500 J ANSWER: The work done by the force is 1500 J. (NOTE: Im sorry. I do not how to get the final speed. I can only get the acceleration.)
