Concept explainers
Numerical and Graphical Reasoning A crossed belt connects a 20–centimeter pulley (10–cm radius) on an electric motor with a 40–centimeter pulley (20–cm radius) on a saw arbor (see figure). The electric motor runs at 1700 revolutions per minute.
(a) Determine the number of revolutions per minute of the saw.
(b) How does crossing the belt affect the saw in relation to the motor?
(c) Let L be the total length of the belt. Write L as a function of

- A driver is traveling along a straight road when a buffalo runs into the street. This driver has a reaction time of 0.75 seconds. When the driver sees the buffalo he is traveling at 44 ft/s, his car can decelerate at 2 ft/s^2 when the brakes are applied. What is the stopping distance between when the driver first saw the buffalo, to when the car stops.arrow_forwardTopic 2 Evaluate S x dx, using u-substitution. Then find the integral using 1-x2 trigonometric substitution. Discuss the results! Topic 3 Explain what an elementary anti-derivative is. Then consider the following ex integrals: fed dx x 1 Sdx In x Joseph Liouville proved that the first integral does not have an elementary anti- derivative Use this fact to prove that the second integral does not have an elementary anti-derivative.
