1) A bug is on the rim of a disk of diameter 14 in that moves from rest to an angular speed of 78 rev/min in 4.4 s.
a. What is the tangential acceleration?
b. What is the tangential velocity of the bug at the end of the 4.4 s?
c. One second after the bug starts from rest, what is its total acceleration?
d. What angle does this acceleration make with ac?
