A bolck of mass 5 kg lies on rough horizontal surface .Whena horizontal force of 24.5 N is applied to the block , at just starts sliding while 19.6N is enough to keep it sliding at uniform velocity find
i) coefficient of static friction
ii)coefficient of kinetic energy
Find also the acceleration of the block when at rest is acted by a force of 24 N and a negligible impulse is imparted.

Ответ:
Each block feels a force of 0.00033 N toward the other one.
Your weight on Earth is equal to the Earth's weight on you.
0.00033 Newton is about 0.0012 of an ounce.
