- Give reasons for the answers to each of the following questions: (a) Can a normal force be horizontal? (b) Can a normal force be directed vertically downward? (c) Consider a tennis ball in contact with a stationary floor and with nothing else. Can the normal force be different in magnitude from the gravitational force exerted on the ball? (d) Can the force exerted by the floor on the ball be different in magnitude from the force the ball exerts on the floor?arrow_forwardA certain orthodontist uses a wire brace to align a patients crooked tooth as in Figure P5.1. The tension in the wire is adjusted to have a magnitude of 18.0 N. Find the magnitude of the net force exerted by the wire on the crooked tooth.

- In many textbook problems, we ignore certain complications such as friction and drag. The problems contain key words that indicate such a simplification is being used. For example, if a surface is described as slippery, it means that we can ignore friction. Look at the previous chapters problem sets. Find five uses of these key words and explain how to interpret each case.arrow_forwardA sled and rider have a total mass of 56.8 kg. They are on a snowy hill. The coefficient of kinetic friction between the sled and the snow is 0.195. The angle of the hills slope measured upward from the horizontal is 19.5. What is the acceleration of the rider? Is the acceleration greater, less than, or equal to your result if a more massive rider uses the same sled on the same hill? Explain.arrow_forwardA block lies motionless on a horizontal tabletop. You apply a force Fapp horizontally to the block, but it does not move. What can you say about the relative sizes and magnitudes of Fapp, the static friction force between the block and the table, and the kinetic friction force between the block and the table?arrow_forward
- A filled treasure chest of mass m with a long rope tied around its center lies in the middle of a room. Dirk wishes to drag the chest, but there is friction between the chest and the floor with a coefficient of static friction s. If the angle between the rope and the floor is , what is the magnitude of the tension required to just get the chest moving? Express your answer in terms of m, s, , and g.arrow_forwardA man exerts a force of 16.7 N horizontally on a box so that it is at rest in contact with a wall as in Figure 6.3. The box weighs 6.52 N. a. Find the static friction force exerted on the box, given the forces being applied, b. If the coefficient of static friction between the wall and the box is 0.50, find the maximum static friction force that may be exerted on the box. Comment on your results.arrow_forwardA textbook rests on a movable wooden plank that is initially parallel to the ground. a. How does the normal force on the book compare to the gravitational force on the book as it rests in the horizontal position? b. If you push down on the book, what happens to the magnitude of the normal force as it rests in the horizontal position? c. The normal force on the book is part of a third-law interaction pair. Describe the third-law partner of this normal force.arrow_forward
- You are trying to slide a heavy trunk across a horizontal floor. The mass of the trunk is 85 kg, and you need to exert a force of 3.3 x 102 N parallel to the ground to make it just begin to move. a). Determine the coefficient of static friction between the floor and the trunk. After the trunk starts moving, you continue to push with this force. The trunk reaches a speed of 2.0 m/s after 5.0 s. Calculate the coefficient of kinetic friction.arrow_forwardA block weighing 60 N rests on a horizontal floor. a) What is the minimum force that will make the block move if the coefficient of static friction is 0.20? b) What is the minimum force that will keep the block moving at uniform speed once it starts moving if the coefficient of kinetic friction is 0.10? please include clear solutions please.arrow_forwardCalculate the magnitude of a normal force on a 22.7 kg block in the following circumstances. a. the block is resting on a level surface. b. the block is resting on a surface tilted up at 40.8 degrees with respect to the horizontal. c. the block is resting on the floor of an elevator that is accelerating upward at 2.53 m.s^2 d. the block is on the level surface and a force of 115 N is exerted on it at an angle of 40.8 degrees below the horizontal.arrow_forward
