Question 6 (1 point) Two washers are connected together by a string that is passed through a frictionless pulley. If one washer has twice as much mass as the second washer, what is the acceleration of the system? Og O 29 O Question 7 (1 point) For uniform circular motion, which of the following statements is true: Centripetal force is directed towards the centre of the circle and centripetal acceleration is parallel to the velocity. Velocity is directed towards the centre of the circle and centripetal acceleration is parallel to the centripetal force. O Centripetal force is directed towards the centre of the circle and centripetal acceleration is parallel to the velocity. O Centripetal acceleration is directed towards the centre of the circle and velocity is perpendicular to the centripetal force.
