JEE PYQ: Rotational Motion Question 22
Question 22 - 2020 (03 Sep Shift 1)
A block of mass $m = 1$ kg slides with velocity $v = 6$ m/s on a frictionless horizontal surface and collides with a uniform vertical rod and sticks to it as shown. The rod is pivoted about $O$ and swings as a result of the collision making angle $\theta$ before momentarily coming to rest. If the rod has mass $M = 2$ kg, and length $l = 1$ m, the value of $\theta$ is approximately: (take $g = 10$ m/s$^2$)
(1) 63$°$
(2) 55$°$
(3) 69$°$
(4) 49$°$
