Problem 37PE

(a) What force should the woman in Figure 9.45 exert on the floor with each hand to do a push-up? Assume that she moves up at a constant speed. (b) The triceps muscle at the back of her upper arm has an effective lever arm of 1.75 cm, and she exerts force on the floor at a horizontal distance of 20.0 cm from the elbow joint. Calculate the magnitude of the force in each triceps muscle, and compare it to her weight. (c) How much work does she do if her center of mass rises 0.240 m? (d) What is her useful power output if she does 25 pushups in one minute?

Step-by-Step Solution:
Step 1 of 3

NEWTON’S FIRST LAW ● the most profound change in understanding the universe up to his time ● developed in the 1660s when the plague was sweeping thru Europe - again ● not published for almost 20 years ● perhaps a true law of nature ● objects at rest stay at rest ● objects in motion stay in motion, unless acted on by an outside force ● the first was common...
