A 5.00 kg mass is at the origin. A 7.00 kg mass is located at x = 0.600m, and a 4.00 kg mass is at x= .900m what is the net gravitational force on 5 kg mass

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
