For the mechanism shown below $\frac{?}{?}$ link $2$ is rotating with an angular velocity ${}_2=4ra\frac{d}{s}$ anticlockwise about $O_2$ and link $4$ is rotating with ${}_4=8ra\frac{d}{s}$ clockwise about ${}_4.$ At the same instant the slider $($link $3)$ has a velocity of slip of $v_3=5\frac{m}{s}.$ The magnifude of the coriolis acceleration is

a$)40\mathrm{.}0\frac{m}{s^2}$

$($b$),80\mathrm{.}0\frac{m}{s^2}$

c$),160\mathrm{.}0\frac{m}{s^2}$

d$)$ None of the above
