Two uniform solid spheres-What is the magnitude

Assignment Help Physics
Reference no: EM13656366

Two uniform solid spheres have the same mass of 1.95 kg, but one has a radius of 0.230 m while the other has a radius of 0.859 m. Each can rotate about an axis through its center.

a) What is the magnitude? Of the torque required bringing the smaller sphere from rest to an angular speed of 317 rad/s in 15.5 s?

b) What is the magnitude F of the force that must be applied tangentially at the sphere's equator to provide that torque?

 

c) What is the corresponding value of F for the larger sphere?
