An object of mass 5kg is on a horizontal surface with a coefficient of kinetic friction .45. The object is connected by a string of negligible mass through a frictionless pulley to an object with a mass of 3kg (hanging vertically off the edge of a table, sort of situation..sorry, this is all paraphrased). Find the acceleration of the two objects.
kinetic friction on object 1:
f = N * u = 9.81m/s^2 * 5kg * .45 = 22.073NFgrav on object 2:
F = a*m = g*m = 9.81m/s^2 *3kg = 29.43NFgrav gets transferred through tension to object one, and the net force in the x direction is:
Fnet = Fgrav -f = 29.43 - 22.073 = 7.36N
----------------------------------------------------------I can't figure out how to get this into acceleration though..little help?
