Mass of the body (m) = 2 kg Height (h) = 25 m Potential energy of the body = mgh 02. A bag of rice weighs 75 kg. To what height is it raised if the work done in lifting it is 4900 ..
Mass of the body (m) = 2 kg Height (h) = 25 m Potential energy of the body = mgh 02. A bag of rice weighs 75 kg. To what height is it raised if the work done in lifting it is 4900 ..Solution:
W = F x S Force acting on the object is given by F = mg [Newton's second law of motion] Mass of the object (m) = 5 kg Distance moved = 2m Therefore, Work done = F x S = 98 J 02. How much work is done, when a force of 25 N displaces an object through 10 m, in the direction of the force ap..

Tutor Vista teachers were knowledgeable and good in explaining to kids with 100% correct answers.... Landon
THE BEST tutoring i have ever seen and experienced! I am done now, but will most definitely come back for more help when needed. Thanks again tutorvista!!! :) - Carter
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
I could not get time to help my daughter with her homework so I looked on net about online tutoring, we tried tutorvista for a week, my daughter liked it, so, now I got her join it.
Looking for More Help!
