Asked by Diane
1. A football player pushes a dummy forwards at a constant 0.85m/s for 11m using 7150 J of energy. The dummy has a mass of 120 kg. Find the force the football player exerts, find the frictional force the dummy exerts.
- for my answer I got 1176N as the force the football player exerts. I don't know how to find the frictional force the dummy exerts. Is the mass necessary to find the frictional force?
2. If given the horizontal and vertical force how would the actual force be found?
Would it be the net force?
