Suppose someone slides a 2kg physics book across the desk. At point A the book is sliding at 3m/s, and it encounters a constant 4N frictional force as it slides 1.5m across the desk to point B. What is the speed of the book at point B? Will pay to who gets it right

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
