Question

If a block is moving to the right at a constant velocity, which must be true? There is exactly one force applied to the block. The net force applied to the block is directed to the left. The net force applied to the block is zero. There must be no forces at all applied to the block. Which of the paths would the cannonball most likely follow if the cannon barrel is launched horizontally? A projectile is launched horizontally from the edge of a cliff (neglect air resistance). Its horizontal speed will change Its vertical speed will change Cannot determine Its vertical speed remains constant A block of mass 3 kg is acted upon by two forces: 8 N (directed to the left) and 11 N (directed to right). What can you say about the block's motion? Continuously changing direction Moving with continuously increasing acceleration Moving with a constant nonzero acceleration Moving at constant velocity According to Newton's second law, the acceleration of an object does not depend on any force on the object is inversely proportional to the net force on the object is directly proportional to net force on the object is always a constant The work done on an object by all forces Equals to the acceleration change of the object Equals to the kinetic energy change of the object Equals to the potential energy change of the object Equals to the velocity change of the object
