Springs & Elastic Potential Energy Video Lessons

Example

# Problem: The spring shown in the figure is compressed 51 cm and used to launch a 100 kg physics student. The track is frictionless until it starts up the incline. The students coefficient of kinetic friction on the 30 30 (Page 231) incline is 0.16 . You may want to review (Page 231) .
