A carousel is spinning at a speed of 100 cm/s, with the outermost horse at a distance 5 m from the center.


Calculate the inward force on the outermost horse, if it weighs 1.5 kg.

A3 x 10-3 N
B3 x 10-2 N
C3 x 10-1 N
D3 x 10 N

Verified Answer :

The speed is 100/100=1 meter per second, so acceleration is 1^2/5=.2.  Then, the net force is 0.21.5 kg = 0.3 N, or 310^-1 N.
