3. A 60 kg boy does 60 push-ups in 40 s. With each push-up he must lift an average of 70 % of his mass a height of 40 cm off the floor. Calculate the following: a) the work the boy does for each push-up, assuming he does work only when he pushes up b) the total work done in 40 s c) the power for this period
