How much work does the intern do by pushing the patient

Reference no: EM13288799

An intern pushes a 72 kg patient on a 15 kg gurney, producing an acceleration of 0.60 m/s2.

(a) How much work does the intern do by pushing the patient and gurney through a distance of 2.5 m? Assume the gurney moves without friction.

(b) How far must the intern push the gurney to do 140 J of work?
