What is happening to the energy at position 2 on the pendulum? use the diagram for the next 2 questions:

A50.0-n box is sliding on a rough horizontal floor, and the only horizontal force acting on it is friction. you observe that at one instant the box is sliding to the right at and that it stops in 2.25 s with uniform acceleration. what magnitude force does friction exert on this box

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Orange juice has a lower or higher viscosity than chocolate syrup
