Question

You and a friend are on a swing set and her swing is slightly longer than yours. If you both start swinging at the same time, from the same height, where will she be after you have completed one complete swing back and forth?

(A) She will be slightly lower than you but moving downward away from you.
(B) She will be slightly lower than you but moving upward toward you.
(C) She will still be at the same height as you.
(D) She will be slightly higher than you.

Answer 1

When swinging on a swing set, the length of the swing affects the period of the swing, which is the time it takes to complete one full swing back and forth. If your friend's swing is slightly longer than yours, she will take slightly longer to complete one full swing. Therefore, after you have completed one complete swing back and forth, your friend will still be swinging and will be slightly lower than you but moving upward toward you.

Step-by-step explanation:

When swinging on a swing set, the length of the swing affects the period of the swing, which is the time it takes to complete one full swing back and forth. The longer the swing, the longer the period. So, if your friend's swing is slightly longer than yours, she will take slightly longer to complete one full swing.

Therefore, after you have completed one complete swing back and forth, your friend will still be swinging and will be slightly behind you in her swing. She will be slightly lower than you but moving upward toward you. So, the correct answer is (B) She will be slightly lower than you but moving upward toward you.
