A 2.8kg 40cm diameter disk is spinning at 260 rpm How much friction force must the brake apply to the rim to bring the disk to halt in 2.0s The answer should be in Newtons?
Torque is equal to friction force (F) * radius (r). Torque is also equal to moment of inertia (I) * Angular acceleration (a). Angular acceleration is equal to rotational velocity * 2Pi/time, which is 2 seconds. So, F = IRa/r, or 45.63 Newtons
