7. Warm Up

8. 1. An object falls, and accelerates at a rate of 9
1. An object falls, and accelerates at a rate of 9.8 m/s/s (until it reaches Terminal Velocity). In the drawing right, what would the speed of the dropped rock be after it fell for 3 seconds? Formula -> Change in velocity = gravity’s acceleration x time in seconds.

9. 2. What is the speed of the rock after 2 seconds? v=g*t
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

10. 3. What is the distance of the rock after 2 seconds? d= g*t2 2
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

11. Time = 0 Time = 1 sec 2.Time = 2 sec 3.Time = 3 sec 4.Time = 4 sec.
4. The rock reaches a speed of 280km/s and does not change its speed until it hits the ground. What is the name of the speed in which the rock does not change speed?
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

1. An object falls, and accelerates at a rate of 9.8 m/s/s (until it reaches Terminal Velocity). In the drawing right, what would the speed of the dropped rock be after it fell for 3 seconds? Formula -> Change in velocity = gravity’s acceleration x time in seconds.

14. 1. What would the speed of the dropped rock be after it fell for 3 seconds? Formula -> Change in velocity = gravity’s acceleration x time in seconds. v=9.8/s2 * 3 sec = 29.4m/s

15. 2. What is the speed of the rock after 2 seconds? v=g*t
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

16. Time = 0 Time = 1 sec 2.Time = 2 sec 3.Time = 3 sec 4.Time = 4 sec.
2. What is the speed of the rock after 2 seconds? v=g*t v= 9.8m/s2*2sec = 19.6m/s
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

17. 3. What is the distance of the rock after 2 seconds? d= g*t2 2
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

18. Time = 0 Time = 1 sec 2.Time = 2 sec 3.Time = 3 sec 4.Time = 4 sec.
3. What is the distance of the rock after 2 seconds? d= g*t d= 9.8m/s2*22 = 19.6 m
Time = 0
Time = 1 sec
2.Time = 2 sec
3.Time = 3 sec
4.Time = 4 sec.

19. Time = 0 Time = 1 sec 2.Time = 2 sec 3.Time = 3 sec 4.Time = 4 sec.
4. The rock reaches a speed of 280km/s and does not change its speed until it hits the ground. What is the name of the speed in which the rock does not change speed?
