Academics

A disc has a radius of 2.20 cm and a mass of 27.0 grams and is initially at rest. Starting at time t=0, two forces are applied tangentially to the rim as indicated, so that t=1.30s the disc has an angular velocity of 2400 RPM counterclockwise. Force F1 has a magnitude of 0.140 N.

A) calc the moment of inertia of the uniform disc in kg m2

B) calc the angular acceleration of the disc in rad/s2

c) calc the net torque acting on the disc in N-m

d) calc the magnitude of F2 in N
