A0.16kg stone attached to a string of length i = 0.22m, is whirled in a horizontal circle with a constant velocity of 4.0m/s. a) calculate the radial i. e the centripetal acceleration of the stone. b) the tension in the string while the stone is rotating. c) the horizontal force on the stone.

PART A)

PART B)

T = 11.6 N

PART C)

Explanation:

PART A)

Centripetal acceleration is given by

now we have

PART B)

Here Tension force of string is providing centripetal force

so we can say

PART C)

Force on the stone in horizontal direction is only tension force

so here we have

real, smaller and upside-down.   so the answer should be b.

answer; equivalent to a one(1) horsepower motor;
