A person pushes a block of mass with a constant speed of straight up a flat surface inclined above the horizontal. The coefficient of kinetic friction between the block and the surface is . What is the net force acting on the block? 0 N 21 N 30 N 51 N Despite a very strong wind, a tennis player manages to hit a tennis ball with her racquet so that the ball passes over the net and lands in her opponent's court. Consider the following forces: 1. A downward force of gravity. 2. A force by the "hit". 3. A force exerted by the air. Which of the above forces is (are) acting on the tennis ball after it has left contact with the racquet and before it touches the ground? 1 only. 1 and 2 . 1 and 3 . 2 and 3 . 1,2 , and 3 . An empty office chair is at rest on a floor. Consider the following forces: 1. A downward force of gravity. 2. An upward force exerted by the floor. 3. A net downward force exerted by the air. Which of the forces is (are) acting on the office chair? 1 only. 1 and 2 . 2 and 3 . 1,2 , and 3 . none of the forces. (Since the chair is at rest there are no forces acting upon it.) . If the woman in question 25 suddenly stops applying a horizontal force to the box, then the box will: immediately come to a stop. continue moving at a constant speed for a while and then slow to a stop. immediately start slowing to a stop. increase its speed for a while and then start slowing to a stop. SAVE AND 25 A woman exerts a constant horizontal force on a large box. As a result, the box moves across a horizontal floor at a constant speed " ". The constant horizontal force applied by the woman: has the same magnitude as the weight of the box. is greater than the weight of the box. is greater than the total force which resists the motion of the box. is greater than either the weight of the box or the total force which resists its motion.
