, = 6.98 rad s -1 and v = 4.30 m s -1

, = 3.75 rad s -1 and v = 4.30 m s -1

and =3.75 rad s -1 and v = 10.0 m s -1

. ONLY ONE of these four options is the correct answer. • For each question, choose the option corresponding to the correct answer. • Answer to each question will be evaluated according to the following marking scheme: Full Marks :+3 If ONLY the correct option is chosen; Zero Marks : 0 If none of the options is chosen (i.e. the question is unanswered); Negative Marks :-1 In all other cases. A bar of mas M= 1.00 kg and length L = 0.20 m is lying on a horizontal frictionless surface. One end of the bar is pivoted at a point about which it is free to rotate. A small mass m = 0.10 kg is moving on the same horizontal surface with 5.00 m s -1 speed on a path perpendicular to the bar. It hits the bar at a distance L/2 from the pivoted end and returns back on the same path with speed v. After this elastic collision, the bar rotates with an angular velocity . Which of the following statement is correct? = 6.80 rad s -1 and v = 4.10 m s -1
