Answer:
19.95 J
Explanation:
The center of mass of the ladder is initially at a height of:
![h_1=\frac{L}{2}sin\theta](https://tex.z-dn.net/?f=h_1%3D%5Cfrac%7BL%7D%7B2%7Dsin%5Ctheta)
The center of mass of the ladder ends at a height of:
=L/2
So, the work done is equal to the change in potential energy which is:
W = PE = ![mg(h_2-h_1)](https://tex.z-dn.net/?f=mg%28h_2-h_1%29)
now ![h_2-h_1= 1-sin\theta](https://tex.z-dn.net/?f=h_2-h_1%3D%201-sin%5Ctheta)
therefore
W = [mgL/2]×[1 - sin(theta)]
W = [(7.30)(9.81)(2.50)/2]×[1-sin(51°)]
solving this we get
W = 19.95 J
Light year is a unit of measure of time that makes use of the speed of light and distance between objects to determine the number of years it will take for the light to travel. We can determine what element the object is made up of by the wavelength of the color.
