Homework Statement This isn't really a homework question- at the end of my last lab, in which we measured the time required to charge and drain a 10micro farad capacitor with a 100k resistor hooked up to a switch and a 9 volt battery our professor asked us what the natural log of voltage...

I think I understand how to begin the problem but when I compute the answers they don't match the selected answers in the back of the book Homework Statement A spring (k=200 N/m) is fixed at the top of a frictionless plane inclined at angle θ=40°. A 1/0 kg block is projected up the plane...

#1- I am assuming that during the collision the momentum of the system is conserved- however, the more I think about it kinetic energy has to be lost from the point at which the projectile is released from the spring... making it an inelastic collision. #2- The mass and velocity were...

Homework Statement This is actually a lab- A ball projectile is fired from a spring gun into a free-hanging pendulum, the pendulum catches the ball and travels a certain vertical measurement. #1-Is this an elastic equation #2-Calculate the kinetic energy the instant before and the...
