I looked up the question and got D- a vacuum
Vai c fude
..........................................................................
Let L = length of the swing.
Let the lowest position of the swing be the reference point.
Therefore in the lowest position,
The height of the swing = 0,
The support for the swing is at height = L.
At 32° swing relative to the vertical,
The height of the swing is
A = L - Lcos(32°) = L[1 - cos(32°)] = 0.152L
Answer:
The amplitude is 0.152*L, where L = length of the swing.
Explanation:
Force (F) = 500 N
Distance (d) = 16 m
work done (w) =?
We know that
w = F * d
= 500 * 16
= 8000 Joule.
The bulldozer performs 8000 Joule.
Hope it will help you :)❤
