A bug is on the rim of a disk of diameter 11 in. that moves from rest to an angular speed of 76 rev/min in 5.3 seconds.
A. What is the tangential acceleration? Answer in units of m/s^2
B. What is the tangential velocity of the bug at the end of the 5.3 seconds? Answer in units of m/s
C. One second after the bug starts from rest, what is its total acceleration? Answer in units of m/s
D. What angle does this acceleration make with ac? Answer in units of degree
11 inch=0.2794 m
76 rev/min=76*2*Pi/60= 7.9587 rad/s
The solution provides detailed explanation how to find rotational, tangential and centripetal acceleration.
