The figure shows the velocity and acceleration of a point like body at the initial moment of its motion. The acceleration vector of the body remains constant. The minimum radius of curvature of trajectory of the body is
(1) \( 2 \mathrm{~m} \)
(2) \( 4 \mathrm{~m} \)
(3) \( 8 \mathrm{~m} \)
(4) \( 16 \mathrm{~m} \)
