Which of the following correctly describes the linear velocity, angular velocity and centripetal acceleration of the particle? B D C A 2 / 5 2) An object is fixed to one end of a Iight rod which rotates in a vertical circle at constant speed. Which graph could represent the variation of tension T in the rod with angle θ? 3 / 5 3) A disc is rotating about an axis through its centre and perpendicular to its plane. A point P on the disc is twice as far from the axis as a point Q. At a given instant, what is the ratio of the linear velocity at P to the linear velocity at Q? 2 ½ ¼ 4 4 / 5 4) The maximum safe speed of a car rounding an unbanked corner is 20 m s–1 when the road is dry. The maximum frictional force between the road surface and the wheels of the car is halved when the road is wet. What is the maximum safe speed for the car to round the corner when the road is wet? 10 m 7.1 m 5.0 m 14 m 5 / 5 5) The diagram shows a disc of diameter 120 mm that can turn about an axis through its centre. 5) The disc is turned through an angle of 30º in 20 ms. What is the average speed of a point on the edge of the disc during this time? π m s–1 1.5π m s–1 2π m s–1 0.5π m s–1 Your score is Restart quiz
