Abug walking on the circular rim of a flower
pot completes one lap around the planter in
9.798 s.
if the radius of the planter is 12.8 cm, how
fast was it traveling?
answer in units of cm/s.
how fast in m/s?
answer in units of m/s

The circumference of any circle is (pi) x (2 x the radius).
The circumference of the rim of the flower pot is (25.6 pi) cm.

Speed of the bug = (distance covered) / (time to cover the distance)

                               =    (25.6 pi cm)  /  (9.798 sec)

                               =           8.208  cm/sec .        (rounded)

To change units:

                         (8.208 cm/sec) x (1 meter / 100 cm)

                     =        0.082  meter/sec          (rounded)

The bug's centripetal acceleration is

                                 (speed in m/s)²  /  (radius in m)

                       =        (0.082 m/s)²  /  (0.128 m)

                       =      (0.006724 m²/s²)  /  (0.128 m)

                       =            0.0525  m/s²

26.4 is about the right time

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.
