A small block A of mass 2 kg is attached to a spring of force constant

1200 \mathrm{Nm}^{-1}

, and rests on a smooth horizontal surface at

x=0

as shown in figure. A second block B of mass 1 kg slides along the surface towards A at

6 \mathrm{~ms}^{-1}

and sticks to it. Assuming that the collision occurs at

t=0

, position

x

(in meter) of block

A

as a function of time

t

is expressed as A small block A of mass 2 kg is attached to a spring of force constant 1200 Nm^ -1 , and rests on a smooth horizontal

A small block A of mass 2 kg is attached to a spring of force constant 1200 Nm^ -1 , and rests on a smooth horizontal

Options

A $x=0.173 \cos 20 t$
B $x=0.1 \cos 40 \pi t$
C $x=-0.173 \sin \frac{\pi}{10} t$
D $\mathrm{x}=-0.1 \sin 20 \mathrm{t}$

Correct answer

D. $\mathrm{x}=-0.1 \sin 20 \mathrm{t}$
