Please help! Somple Work-energy problem!
Sam works at an amusement park. A boat of children on a water ride comes the the pier at the end of the ride. They are moving at a constant speed of 1.2 m/s, and the loaded boat has a mass of 1200kg. Sam slows the boat down by pushing on it until it...

Simple Spring Problem Help!
A spring gun fires an object of mass 2.1 kg horizontally across a frictionless table. The spring has a spring constant of 19 N/m and is initially compressed by 3.6 cm. What is the speed of the object as it leaves the spring gun?
I can not figure out this problem...
I'm not sure. My Teacher just through this problem at us without much explanation. We haven't even covered springs. I'll look into your question though I am not sure I fully understand it.
Thanks!
A force of 8.4 N holds an ideal spring with a 31.9 N/m spring constant in compression. How much potential energy is stored in the spring?
I would think it would be PE =mgh
to get m you divide the force/g
but now I am not sure what to do after that.
Any help would be great!
2) A Uniform Boars has a mass of 1.5kg and length of 100cm, Note the Weight is negligible.
A) Where should it be supported so that it will balance a 10g mass places at an end, a 60kg mass on the other end, and a 40kg mass placed 30 cm to the 10g mass?
The answer should be 0.511m

A uniform ladder of a length 5m and a mass 15 kg leans against a wall, making a 45 degree angle with the ground. The wall is capable of supporting a maximum of 500 N.
A fireman must climb the ladder to it's midpoint, what is the max mass that the fireman can be without collapsing the...
