Question
The angular position of a rod varies as 23.7t2 radians from time
t = 0. The rod has two beads on it as shown in the following figure, one at
r1 = 15 cm from the rotation axis and the other at r2 = 42 cm from the rotation axis. (Note: figure may not be drawn to scale.)
 
 
(d) What are the tangential accelerations of the beads at
t = 7 s?
(Enter the magnitudes in m/s2.)
at, 1
= m/s2
at, 2
= m/s2
(e) What are the centripetal accelerations of the beads at
t = 7 s?
(Enter the magnitudes in m/s2.)
ac, 1
= m/s2
ac, 2
= m/s2
