Physics question involving tangential acceleration, tangential velocity and centripetal acceleration?
(a)What is the tangential acceleration of a bug on the rim of a 10-in. diameter disk if the disk moves from rest to an angular speed of 78 rev/min in 3.0s.? (b) When the disk is at its final speed, what is the tangential velocity of the bug? (c) One second after the bug starts from rest, what are its tangential acceleration, centripetal acceleration and total acceleration?
