What is the magnitude and direction of acceleration for a stone tied to the end of a 80 cm long string, whirling in a horizontal circle with a constant speed, if the stone makes 14 revolutions in 25 s?

Options

A11.1 m/s² towards the center of the circle
B11.1 m/s² away from the center of the circle
C9.9 m/s² towards the center of the circle
D9.9 m/s² away from the center of the circle

Correct answer

C. 9.9 m/s² towards the center of the circle

Step-by-step solution

Correct Option is : (C)
