1. Why do we use static friction instead of kinetic friction for a rolling object? 2. Why do we ignore the effects of friction in the conservation of energy?

Please answer as many as possible! Thanks! 1. If the kinetic energy of a particle is zero, what is its linear momentum? 2. If the speed of a particle is doubled, by what factor is its momentum changed? By what factor is its kinetic energy changed? 3. If two particles have equal kinetic...

Hi, the AP test is approaching and I'm struggling with these two Calculus questions and need some guidance. If you can provide a general (or detailed if possible =)) explanation on how you solved the problem, or the strategy you used for the problem, I would be extremely grateful. Solving even...
