Question

In the figure acceleration of bodies A, B and C are shown with directions. Values b and c are w.r.t ground whereas a is acceleration of block A w.r.t wedge C. Acceleration of block A w.r.t ground is

$\sqrt{(b + c)^{2} + a^{2}}$
$c - (a + b) c o s q$
$\sqrt{(b + c)^{2} + c^{2} - 2 (b + c) c c o s q}$
$\sqrt{(b + c)^{2} + c^{2} + 2 (b + c) c c o s q}$

The correct answer is: $c minus left parenthesis a plus b right parenthesis c o s invisible function application q$
