WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s. Web21 dec. 2024 · The formula for calculating work is Work = Force x Distance. Hence, to calculate the distance from force and work, proceed as follows: Determine the work done, W, when the force, F, is applied. Divide the work done, W, by the applied force, F. Congrats, you have calculated the distance from the force and work!
