A 15 -kg collar travels down a smooth slope which is described by the function: y = 0.1 x² as shown. If at location 1 its speed is 20 m/s, determine its speed when it gets to position 2. The spring has original length (unstretched length) = 7 m and stiffness k =50 N/m. Note: you must use Principle of Work and Energy y = 0.1 x? 6 m - 10 m
