EXERCISE 6 1. A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25° downward from the horizontal. Find the work done by the shopper as she moves down a 50-m length of aisle. 1.6 kJ 2. A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the crate moves at constant speed‚ find (a) the work done by the 150-N force and (b) the coefficient of kinetic friction between the crate and surface. 900J

Arc Length The definition of radian measure s = rθ The unit circle An angle of 1 radian Proof of the theorem IT IS CONVENTIONAL to let the letter s symbolize the length of an arc‚ which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally‚ "stretches under." Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π. π | = | C D | . |

The Reflex Arc Reflex actions are the way the body responds rapidly to painful situations or the threat of painful situations. The reflex are is the mechanism by which the response occur The reflex arc is the name given to the pathway (or circuit) along which the initial stimulus and the corresponding response message travel There are five parts to a reflex arc: 1.) The Receptor‚ which receives the initial stimulus 2.) The Sensory (afferent) Nerve‚ which carries the impulse to the spinal cord or
