1. The problem statement, all variables and given/known data A Pulley has mass M=4 kg and radius R=0.4 m. Assume that it is a uniform solid disk so that its moment of inertia is I= .5MR^2. A massless cord is wrapped around it and a tension force Ft is applied. The pulley starts from rest. After the tension force has been applied for 6 seconds, the angular speed has reached T=60 rads/s. 2. Relevant equations a.) What is the pulley's angular acceleration? b.) What is the linear (tangential) acceleration of a point on the rim of the pulley? 3. The attempt at a solution a.) V=(2*pi*R)/T V= .418 m/s w=v/r w=1.045 rads/sec angular acceleration= w2-w1/t2-t1 = (1.045-0)/(6-0) = .15 rads/s^2 b.) Tangential acceleration= r*alpha =.o2 m/s^2 Can anyone please tell me if this is correct?? Thank you thank you!
