Question

25. How long does it take a child on a swing to complete one swing if her center of gravity is 4.00 m below the pivot?

Please include all of your steps with the solution.

Answer 1

• Length=l=4m

`\\ \rm\rightarrowtail T=2\pi\sqrt{(l)/(g)}`

`\\ \rm\rightarrowtail T=2\pi\sqrt{(4)/(9.8)}`

`\\ \rm\rightarrowtail T=2\pi(0.63887)`

`\\ \rm\rightarrowtail T=1.27774\pi`

`\\ \rm\rightarrowtail T=4.012s`
