    How Much Work Did Sam Do to Stop the Boat on the Ride?

    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...

    Solving a Simple Spring Problem: Finding the Speed of a Launched Object

    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...

    Calculate Potential Energy of 8.4N Spring w/31.9 N/m Constant

    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!

    Calculate Potential Energy of 8.4N Spring w/31.9 N/m Constant

    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!
