A simple harmonic oscillator consists of a block attached to a spring with k = 200 N/m. The block slides on a frictionless horizontal surface, with equilibrium point x = 0.  A graph of the block’s velocity v as a function of time t is shown. Correctly match the required information in the left column with the values (in SI units) given in the right column $(use{\pi }^2=10)$

	Column – I		Column – II
A)	The block’s mass in kg	P)	– 0.20
B)	The block’s displacement at t = 0 in metres	Q)	– 200
C)	The block’s acceleration at t = 0.10s in $m/s^2$	R)	0.20
D)	The block’s maximum kinetic energy in Joule	S)	4.0
