Question

If a particle takes $$0.5\,\sec$$ to reach position of minimum velocity from previous such position, then

A. $$T = 6\,\sec ,\,v = \frac{1}{6}\,Hz$$

B. $$T = 2\,\sec ,\,v = 1\,Hz$$

C. $$T = 3\,\sec ,\,v = 3\,Hz$$

D. $$T = 1\,\sec ,\,v = 1\,Hz$$

Answer : $$T = 1\,\sec ,\,v = 1\,Hz$$

Solution :
$$\eqalign{ & \frac{T}{2} = 0.5\,\sec \Rightarrow T = 1\,\sec \cr & v = \frac{1}{T} = 1\,Hz \cr} $$
