According to ewton's First Law, the net force on the bookmust be zero since the book is not moving. The force that explains why books do not fall through tablesis called the normal force FN. It is a perpendicular contact force exerted by a surface.In the drawing at the right, abook is sitting on the table. Thebook is not moving, so the netforce on it must be zero.FNFgQ11 How does the table “know" how much normal force to exert as the weight of the object placed ontop of it changes?

To maintain a constant speed, the force provided by a car's engine must equal the drag force plus the force of friction of the road (the rolling resistance). (a) What are the magnitudes of drag forces at 70 km/h and 100 km/h for a Toyota Camry? (Drag area is 0.70m2) (b) What is the magnitude of drag force at 70 km/h and 100 km/h for a Hummer H2? (Drag area is 2.44 m2) Assume all values are accurate to three significant digits.
Unlike most of the other muscles in our bodies, the masseter muscle in the jaw, as illustrated in the figure, is attached relatively far from the joint, enabling very large forces to be exerted by the back teeth. This is shown in the figure below, where a person is biting down on a bullet placed between the back teeth. (FM= 210 N and rR = 4.1 cm.) (a) Using the information in the figure, calculate the magnitude of the force exerted by the teeth on the bullet. (b) Calculate magnitude of the force on the joint.
