| **The body moves evenly around the circumference. Determine the change in its centripetal acceleration with a decrease in its speed by 3 times and an increase in the radius of the circle by 4 times.**

Centripetal acceleration formula:

a = v ^ 2 / r

First condition:

speed V = v / 3

a1 = V ^ 2 / r = (v / 3) ^ 2 / r = v ^ 2/9 * r – acceleration will decrease 9 times relative to the initial

Second condition:

radius R = 4 * r

a2 = v ^ 2 / R = v ^ 2/4 * r – acceleration will decrease by 4 times relative to the initial
