As you may have noticed I've got a bit of a rollercoaster theme going.(adsbygoogle = window.adsbygoogle || []).push({});

My problem now is i have an 800 kg cart and I need to calculate the work done by bringing it to the top of the rollercoaster. The slope of the lift is 20 degrees and the maximum height is 30 m. From this i calculated the distance it will travel to get to the top is 87.7m. Now I'm at a snap because I have the distance but I dont have the force so I cant think of how to calculate work. Any suggestions?
