1 Which is a vector quantity? (1) distance (3) power (2) speed (4) force 2 The diagram below shows a granite block being slid at constant speed across a horizontal con- crete floor by a force parallel to the floor. Which pair of quantities could be used to deter- mine the coefficient of friction for the granite on the concrete? (1) mass and speed of the block (2) mass and normal force on the block (3) frictional force and speed of the block (4) frictional force and normal force on the block 3 An object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second 2 in the direction of its motion for a dis- tance of 5.0 meters. What is the final speed of the object? (1) 6.0 m/s (3) 14 m/s (2) 10. m/s (4) 36 m/s 4After a model rocket reached its maximum height, it then took 5.0 seconds to return to the launch site. What is the approximate maximum height reached by the rocket? [Neglect air resis- tance.] (1) 49 m (3) 120 m (2) 98 m (4) 250 m 5 The diagram below shows a student throwing a baseball horizontally at 25 meters per second from a cliff 45 meters above the level ground.
