so use the formula 1/2mv^2+1/2Iw^2?

so fnet = total mass * acceleration fnet = the sum of all forces on both objects making it total mass * linear acceleration = sum of all forces linear acceleration = 9.8(-40+55+7.5)/(40+55+7.5) linear acceleration = 2.15rad/s^2

for Ma I got 9.8*40=392 Mb 9.8*55=539 making the total force is 147. I also know that to find net torque of the pulley its =mratan. What should I attempt next?

Homework Statement Two masses, mA = 40.0 kg and mB = 55.0 kg, are connected by a massless cord that passes over a pulley that is free to rotate about a fixed axis. This device is known as an Atwood’s Machine. The pulley is a solid cylinder of radius R = 0.360 m and mass of 7.50 kg. 1...
