A hoop of mass 0.1kg and radius 0.25m is rotating in a horizontal plane with angular momentum of 4.0kgm2

/s. A lump of clay of mass 0.2kg is placed (gently) on the hoop.

Show that the angular velocity of the hoop reduces.​

Gunpowder residue is most likely to show up where on a shooters hands

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
