PHYSICS 1301 (COLLEGE)
As shown in the figure below, two masses m1 = 4.10 kg and m2 which has a mass 50.0% that of m1, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m1 and m2 start from rest, after they have each traveled a distance h...

Math HELP PLEASE
A particle P of mass m=1 moves on the x-axis under the force field F=36/(x^3) - 9/(x^2) (x>0). (a)Initially P is projected from the point x=4 with speed 0.5. Show that P oscillates between two extremes points and find the period of the motion. (b)Show that there is a single...
