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.
