Thanks, mate. When I first glanced at that I was thinking 150. After some shock I finally understood it.

Hi all. I have come across a question in the kenetic energy section on a physics classroom website. The question asks you to find the speed, and have given the energy output and mass. The energy is 12,000 joules and the mass 40kg. The formula for calculating the kinertic energy is KE =...

Oh thanks. I didn't realize it was something you couldn't work out in your head.

Thanks guys. But, rollcast, how did you find the number 0.866 from a 30 degree angle?

Hi all. I am trying to learn more on physics, and am at the subject on calculating work done. The formula to calculate work done is Work done = Force * Dislacement * consine(theta). I am on a question which explains: a 100N force is applied at an angle of 30 degrees to the horizontal to...
