well you know i have the same home work con physics haha and it's chapter 8 right second question haha. i think; if you want to lift a barbell three times as high you have to give three times the work (W)
This weightlifter did work on the barbell to lift it over her head.
Work = Force x distance So since the barbell is 500N and the barbell travels 2.2 meters it becomes 500N x 2.2m = 1100 joules (N x m)
5105.8 J
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.
Obviously will does more work because Ben does nothing.
Any kind of deadlifts will also work your traps. .
If we are talking about an industrial piercing, yes you need two piercings. however you can still wear a barbell in one piercing provided that it is fitted to work in that single piercing.
you get the sum and times with the subject total and times
I don't know what you mean by momentary muscular failure. Surely if this happens he won't succeed in lifting the barbell? Lifting a barbell or indeed any muscular work done involves chemical changes in the muscles which provide the energy required, in this case raising the weight against the force of gravity. The energy used to lift a weight m kg a height of h meters is 9.81 x m x h joules.
There are certain times yes, but not always.
Sixteen divided by two times itself three times
