A 1400 kg car is traveling on a level road at a constant speed of 26.8 m/s (60 milesper hour.) The drag force exerted by air on the car and the frictional force exerted by theroad on the car’stires add to give a net force of 680N pointing opposite to the direction ofthe car’s motion. What is the rate of work done (power) by the air and the road on thecar?

How to calculate voltage drop in a series circuit

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .

Which model displays the change in a gas when the temperature of the gaseous system decreases?
