  9. Use significant figures 7. What is the sum of 3.045 g and 2.5 g? • What is the volume of a rectangular solid which measures 4.00 cm X 4.2 cm X 3.42 cm? 5.5 g 57 cm3

  10. significant figures 9. The speed of sound in air is 341 m/s. What is the speed of sound in inches per second? 10. Which of the following measurement has 4 significant figures? A. 48. 440 g C. 1420 g B. 42. 0032 g D. 42.30 g 13,400 in/s D

  11. Relationship of Variables Refer to this formula: I = P/4r2 11. What is the relationship of I and P? 12. What is the relationship of I and r? DIRECT PROPORTIONALITY INVERSE SQUARE PROP.

  12. Horizontal Motion A man is traveling along a straight path. He walks 20 m to the east for the first 10.0s and then walks at the rate of 5 m/s on the same direction for another 10 s. 13. What is the average velocity of the man for the first 10 s? 14. What is the total distance traveled by the man? 2 m/s 70 m

  13. 15.What is the time when the object started moving to the negative direction? 16.What is the total displacement of the object? 50 s 25 m

  14. 17.Identify the direction of velocity and acceleration from t= 10 s to t= 12 s18. What is the acceleration for the first 2 s? V to the east ; a to the west 4 m/s2

  15. Kinematics 2 pts. A car accelerates at a constant rate from 15m/s to 25 m/s while it travels a distance of 125 m. How long does it take to achieve this speed? 6. 25 s

  16. Remember the following: • The slope of d vs t graph is equal to the velocity of the object. • The slope of v vs t graph is equal to the acceleration of the object. The area under the line or curve is the displacement.

  17. The car is moving to the right with constant positive speed from t=0 to t=50. The car is moving back at constant speed from t=50s to t=60 s. The car is at rest from t= 60 s to t= 90 s. The car starts to move to the right at constant speed from t=90s to t=110s. Interpreting d vs t graph

  18. The car is accelerating to the right from t=0s to t=2s. The car is traveling at constant velocity from t=2s to t=10s. The car is decelerating (slowing down) from t=10s to t=12s. The car is traveling at constant velocity from t=12s to t =16 s. Interpreting v vs t graph

  19. Pray… Believe… Prepare… Trust the Lord!
