A ball of mass 150 grams moving with a velocity of 15 m s -1 is brought to rest by a player in 0.1 seconds calculate the force acting on the hands of the players

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

The material that keeps its new shape after it is stretched is called?

What is friction? how does it affect the motion of an object?
