WebThe net work is the change in kinetic energy of the object, which in this case would be zero because the velocity does not change (remember KE is 1/2mv^2). But the work that we have done on the object is not zero because we are referring only the force we exerted, not the net force. We could also ask how much work gravity did on the object, and ... 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.
