Physics Question on Uniform Circular Motion
A stone tied to 180cm long string at its end is making 28 revolutions in horizontal circle in every minute The magnitude of acceleration of stone is x1936ms−2 The value of x _____ ( Take π=722 )
Answer
The correct answer is 125
a=ω2R=(6028×2π)2×1.8
=(6056×722)2×1.8
=225(44)2×1.8
=2251936×1.8
=1251936
x=125
