The Toyota Prius has a drag coeffi cient of 0.25, a frontal area of 23.4 ft2, and an empty weight of 3042 lbf. Its rolling resistance coeffi cient is Crr 5 0.03, that is, the rolling resistance is 3 percent of the normal force on the tires. If rolling freely down a slope of 88 at an altitude of 500 m, calculate its maximum velocity, in mi/h.

Which of the following represents an upside-down image?

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
