CLMECH-GT91XD

As part of a rollercoaster ride, the cars go through a vertical circular loop with a radius of $25.0\space m$. At the top of the loop, the cars have slowed to a speed of $5.00\space m/s$.

How many "$g's$" do the passengers experience at the bottom of the loop? Assume friction and air resistance are negligible.

A

$0.100\space g's$

B

$4.00\space g's$

C

$4.10\space g's$

D

$40.2\space g's$
