What are the recent breakthroughs in physics in the fields of theoretical mechanics, optics & photics, meterials sciences, quantum mechanis, elecromagnetics, and statistical mechanis? :smile:
Using only one equation of motion, how will you solve this:
Suppose a the tteacher's hand is 1m from the floor, and the teacher flicked a chalk upwards at 2m/s. How long will it take for the chalk to reach the floor?
I can't seem to use only one equation, it's always two equations or three...
