Because the velocity of an object depends on 7. as well as 8. the velocity of an object can change even as the 9. of the object remains constant. Imagine race cars going around an oval track. Even if their 10. remains constant, their velocity changes because the 11. of their motion is changing. If a car is traveling on a street and slows down, its speed 12. and the car has negative 13. Then the car speeds up, giving it positive 14. When the car was slowing down, the 15. was in the opposite 16. of the 17. To calculate a change in velocity, subtract the 18. from the If the direction of motion does not change and the object moves in a straight line, the change in velocity is the same as the change in 20. 19.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
