Chapter 1: Q13DQ (page 356)

13. The mighty Zimbo claims to have leg muscles so strong that he can stand flat on his feet and lean forward to pick up an apple on the floor with his teeth. Should you pay to see him perform, or do you have any suspicions about his claim? Why?

Short Answer

Expert verified

There is a suspicion about his claim.

Step by step solution

01

Center of gravity

The center of gravity is the point on a body where the total weight of the body is concentrated.

02

Suspicions about the claim

When the mighty zimbo changes his center of gravity he leans and his body moves forward to pick the apple.

He falls as the center of gravity changes because the mass center will apply the non-zero torque on the body.

So the mighty zimbo uses any tool at the center of gravity that prevents him from falling. Hence, this is the suspicion about his claim.

A hammer with mass m is dropped from rest from a height h above the earth’s surface. This height is not necessarily small compared with the radiusof the earth. Ignoring air resistance, derive an expression for the speed v of the hammer when it reaches the earth’s surface. Your expression should involve h,, and(the earth’s mass).

A rubber hose is attached to a funnel, and the free end is bent around to point upward. When water is poured into the funnel, it rises in the hose to the same level as in the funnel, even though the funnel has a lot more water in it than the hose does. Why? What supports the extra weight of the water in the funnel?

You are given two vectors A→=−3.00i^+6.00j^andB→=7.00i^+2.00j^ . Let counter- clockwise angles be positive. (a) What angle doesA→ make with the +x-axis? (b) What angle doeslocalid="1662185215101" B→ make with the +x-axis? (c) Vectorlocalid="1662185222673" C→ is the sum of localid="1662185243350" A→andlocalid="1662185251585" B→ , so localid="1662185235469" C→=A→+B→What angle does localid="1662185258976" C→make with the +x-axis?

(a) If, as is typical, each of them breathes about 500 cm3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year? (b) What would the diameter (in meters) of the space station have to be to contain all this air?
