A mass is attached to a spring such that it can slide back and forth horizontally on a frictionless surface. Experimentally, it was determined that when the spring is compressed or stretched a distance s it pushes or pulls back with a force proportional to the s in a way that can be described with the equation F = -ks.

Create a VPython program that uses a spring with k = 515 N/m compressed to 4.6 cm to find the speed of a 405 grams mass at the point where the spring is no longer compressed.

You use a spring with k = 515 N/m compressed 4.6cm to launch a mass of 405 grams out of a projectile launcher. As soon as the mass leaves the launcher, it slides 98cm along a 1.0 meter tall table that has a coefficient of friction of k=0.12. How far from the edge of the table does the mass land?
