A link OB is rotating with a constant angular velocity of 2 rad/s in counter clockwise direction and a block is sliding radially outward on it with an uniform velocity of 0.75 m/s with respect to the rod, as shown in the figure below. If OA = 1 m, the magnitude of the absolute acceleration of the block at location A in m/s² is

Correct Option: C
αt = 2vω = 2 × 0.75 × 2 = 3
| αr = | = 4; | |
| r |
a = √a²t + a²r = √3² + 4²
a = 5 m/s²
