A strong man of mass 90kg supports a log of mass 50kg on his head, steadying it with his upraised arms. What is the normal contact force from his feet on the floor?
He suddenly lifts the log above his head, giving it an acceleration of 2ms^-1. What is the normal contact force on the floor while he does this?
It'd help a lot if you could make clear which part your answering, thanks.
