N A 28.0-kg block is connected to an empty 2.00-kg bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.45 and the coefficient of kinetic friction between the table and the block is 0.32. Sand is gradually added to the bucket until the system just begins to move. 28.0 kg J I point Calculate the acceleration of the system in m/s2. Type your answer... 6 1 point Da Calculate the mass of sand added to the bucket in kg. Type your answer... 13 DO Circles A 1200 kg car is moving on a curved road with a radius of curvature of 30 meters. The car is traveling at a constant speed of 25 m/s around the curve. Determine: 7 1 point The magnitude of the net force acting on the car. Type your answer... 8 1 point The frictional force between the tires and the road if the coefficient of friction is 0.3.
