A stone tied to the end of a 1 m long string is whirled in a horizontal circle with a constant speed. If the stone makes 22 revolutions in 44 s, what is the magnitude and direction of acceleration of the stone?
- \(\frac{\pi^{2}}{4}\) m/s2 and direction along the radius towards the centre
- \(\pi^{2}\) m/s2 and direction along the radius away from centre
- \(\pi^{2}\) m/s2 and direction along the radius towards the centre
- \(\pi^{2}\) m/s2 and direction along the tangent to the circle
Answer
(C) ^ 2 m/s 2 and direction along the radius towards the centre
