1)
mass , m = 16 kg
radius , r = 0.2 m
a)
the net torque , T = 50 * cos(35) * r + 70 * 0.1 - 60 * sin(75 ) * r
T = 50 * cos(35) * 0.2 + 70 * 0.1 - 60 * sin(75 ) * 0.2
T = 3.6 N.m
the net torue is 3.6 N.m clockwise
b)
the angular accelration , alpha = net torque /moment of inertia
alpha = 3.6 /( 0.5 * m * r^2) = 3.6 /( 0.5 * 16 * 0.2^2) rad/s^2
alpha = 11.25 rad/s^2 clockwise
