A body of mass 10kg moving in a circle of radius 2cm completes 3 circles in 3 seconds. Use pi and 3.14. Calculate the acceleration of the body.​

Respuesta :

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
