LEVEL # 1 Questions Conceptual Problems Q.6 A particle, situated in an object, moves with based on Q.1 A wheel starts rotating from rest and attains an angular velocity of 60 rad/sec in 5 seconds. The total angular displacement in radians will be : (A) 60 (B) 80 (C) 100 (D) 150 Q.2 A body rotates at 300 rotations per minute. The value in radian of the angle described in 1 sec is (A) 5 (B) 5 (C) 10 (D) 10 Q.3 A chain couples and rotates two wheels in a bicycle. The radii of bigger and smaller wheels in a bicycle. The radii of bigger and smaller wheels are 0.5m and 0.1. respectively. The bigger wheel rotates at the rate of 200 rotations per minute, then the rate of rotation of smaller wheel will be - (A) 1000 rpm (B) 50/3 rpm (C) 200 rmp (D) 40 rpm angular acceleration of 6 rad/sec2 and with 2 rad/sec angular velocity. If the radius of the circular path is 1m, its total acceleration in m/sec2 will be : (A) 1 (B) 100 (C) 10 (D) Q.7 A particle starts from rest under
