4. Checking of Attendance

5. Classroom Rules

6. Guess me!

7. θ Theta/ Angle of Projection

8. V Initial Velocity

9. V y Peak of the Parabola

10. D ymax (H)Highest point or Maximum Height

11. R Range

12. In addition….

13. Time of flight Time taken to reach the peak/highest point of the height

14. Total time of flight Time taken to reach the peak from the starting point down to the ending point

15. OBJECTIVES

16. OBJECTIVES Identify the different symbols use for each quantity in solving the height and range of projectile Calculate the possible height and range that may achieve by a projectile Give the importance of knowing the height and range of a projectile in relation to sports 01 02 03

17. OBJECTIVES Identify the different symbols use for each quantity in solving the height and range of projectile 01

18. OBJECTIVES 02 Calculate the possible height and range that may achieve by a projectile

19. OBJECTIVES Give the importance of knowing the height and range of a projectile in relation to sports 03

20. Give me a Label!

21. Y X T=2t Vy =0 ay=-g

22. Matching Type

23. 1. Projectile reached its highest point T= Vy – V0y / g 2. H or maximum height Dymax = ( Vy )2 – ( Voy ) 2 / 2g 3. Total time flight T = 2t 4. Range R = V0x x ttotal 5. Initial Velocity along the x-axis v 0x = v cos θ 6. Initial velocity along the y-axis v 0y = v sin θ

24. Let’s Try

25. A firefighter aims a fire hose upward, toward a fire in a building. The water leaving the hose with a velocity of 32.0 meters per second . If the firefighter holds the hose at an angle of 78.5 degree, what is the maximum height of the water stream?

26. 1. Identify the given quantities in the problem

27. Given: Vo = 32.0 m/s θ = 78.5 degree

28. 2. Calculate the value of V0x and V0y

29. 3. Calculate the value of time flight

30. 4. Calculate the value of total time of flight

31. 5. Calculate the value of height

32. 6. Calculate the value of range
