The sun's energy is refferd to solor energy
Hi there!
Recall the equation for centripetal force:
![F_c = \frac{mv^2}{r}](https://tex.z-dn.net/?f=F_c%20%3D%20%5Cfrac%7Bmv%5E2%7D%7Br%7D)
We can rearrange the equation to solve for 'r'.
Multiply both sides by r:
![r * F_c = mv^2](https://tex.z-dn.net/?f=r%20%2A%20F_c%20%3D%20mv%5E2)
Divide both sides by Fc:
![\boxed{ r= \frac{mv^2}{F_c}}](https://tex.z-dn.net/?f=%5Cboxed%7B%20r%3D%20%5Cfrac%7Bmv%5E2%7D%7BF_c%7D%7D)
A surface in which is flat or very soft to the touch and reduces splinters or anything sticking out, having an surface which does not have lumps, or indentations.
Tension in the rope due to applied force will be given as
![F = 142 N](https://tex.z-dn.net/?f=F%20%3D%20142%20N)
angle of applied force with horizontal is 37 degree
displacement along the floor = 6.1 m
so here we can use the formula of work done
![W = F d cos\theta](https://tex.z-dn.net/?f=W%20%3D%20F%20d%20cos%5Ctheta)
now we can plug in all values above
![W = 142 * 6.1 * cos37](https://tex.z-dn.net/?f=W%20%3D%20142%20%2A%206.1%20%2A%20cos37)
![W = 691.8 J](https://tex.z-dn.net/?f=W%20%3D%20691.8%20J)
So here work done to pull is given by 691.8 J
