(a) What is the magnitude of the tangential acceleration of a
bug on the rim of a 12.0-in.-diameter disk if the disk accelerates
uniformly from rest to an angular speed of 77.0 rev/min in 3.70
s?
m/s2
(b) When the disk is at its final speed, what is the magnitude of
the tangential velocity of the bug?
m/s
(c) One second after the bug starts from rest, what is the
magnitude of its tangential acceleration?
m/s2
(d) One second after the bug starts from rest, what is the
magnitude of its centripetal acceleration?
m/s2
(e) One second after the bug starts from rest, what is its total
acceleration? (Take the positive direction to be in the direction
of motion.)
magnitude | m/s2 |
direction | ° from the radially inward direction |
