Answer:
0
Explanation:
The formula for finding acceleration is a = v/t (velocity/time)
so first we must find the velocity
the formula for finding velocity is v = d/t (displacement/time)
and speed is the distance traveled/time
so you must find the distance traveled
the circumference of a circle with a radius of 2cm is 12.57
and the body of mass traveled this circle 3 times
so 12.57 times 3 is 37.71
so that was the total distance traveled, and this was completed in three seconds
so s = 37.71/3 which is just 12.57 = 37.71/3
if we assume that these circles began and ended in the same place, that would make the displacement of the body of mass 0
so v=d/t v=0/3 0=0/3
meaning a=0/3 0=0/3
