A 2520-lb car travels up the 8-percent incline shown. The car is
subjected to a 65-lb aerodynamic drag force and a 45-lb force due
to all other factors such as rolling resistance. Determine the
power output required at a speed of 68 mi/hr if (a) the
speed is constant and (b) the speed is increasing at the
rate of 0.05g.

A car has a mass of 1850 kg and travels down a 15 degree incline at a constant speed of 100 km/hr. The car rolls on tires that have a radius of 44.95 cm, which roll without slipping. What is the torque being provided by each of the Jeep's brakes? (Assume friction is evenly distributed) and what is the power of each of the breaks?Is mechanical energy conserved?

A car travels at a constant velocity of 90 km/h along an
expressway under-ambient temperature and pressure conditions. The
width of the car is 1.5 m while its height is 1.2 m. The wheelbase
(length between the front and rear wheels) is 2.5 m. The drag
coefficient is 0.22.
[Use
air, ambient density of the air = 1.12 kg/m3 and,
fuel, density of the fuel = 930 kg/m3. You may neglect
any energy contained in the exhaust gases and any...
