4 Two horizontal forces are applied to a 67. Which graph best represents the motion of 2.0-kilogram block on a frictionless, horizontal an object that has no unbalanced force acting surface, as shown in the following diagram. on it? F1 = 2.0 N F2 = 8.0 N 2.0 kg Velocity Acceleration Frictionless horizontal surface Time Time (1) (3) The acceleration of the block is (1) 5.0 m/s to the right (2) 5.0 m/s to the left Displacement Momentum (3) 3.0 m/s to the right (4) 3.0 m/s to the left Time Time (2) (4) 65. Which graph best represents the motion of an 68. Four forces act on an object, as shown in the object on which the net force is zero? following diagram. 30. N Distance Distance Speed Speed 40. N - Time Time Time Time (1) (2) (3) (4) 66. The vector diagram below represents force F 30. N acting on point P If the object is moving with a constant velocity, Force what is the magnitude of force F? P . 69. A 1.0-kilogram book
