Consider an object with a mass of 12.5 kg moving at a constant speed in a circular path with a radius of <11.30> m. The object makes one full revolution in <16.60> seconds. Calculate the centripetal acceleration of the object. Give your answer in m/s2 and with 3 significant figures.

Question

I know you have to use the equation ( a=v^2/r) but I don't know how to figure out the Velocity in the equation. I am confused

Answer 1

velocity = circumference / period

v = (2 * π * 11.30 m) / 16.60 s

plug it in and crank the crank
