An arrow is shot straight up into the air at a speed of 98 m/sec. What is the maximum height reached by the arrow? You may neglect air friction. Select one: a. 98 meters b. 490 meters c. 980 meters d. 1,470 meters

2. omnomnom

Lol seriously?

3. dpaInc

is this from the moon, pluto, saturn?

4. saifoo.khan

Mercury!

5. omnomnom

EARTH!

6. omnomnom

ITS earth

7. dpaInc

sorry, i don't have the gravitational constant for mercury... :(

8. dpaInc

come to think of it, i don't have it for those planets/moon i mentioned...

9. saifoo.khan

v^2 = u^2 + 2as. 0^2 = 98^2 + 2(-9.81)s

10. omnomnom

LOL :D

11. saifoo.khan

lol @dpaInc

12. omnomnom

and saifoo you just confused me further

13. saifoo.khan

Why so?

14. saifoo.khan

Where so?

15. omnomnom

idk the equation

16. saifoo.khan

Don't you know the formulas? D:

17. omnomnom

i do but what the hell did you write?

18. saifoo.khan

What's so difficult in this? v^2 = u^2 + 2as. 0^2 = 98^2 + 2(-9.81)s

19. omnomnom

okay $V^2 = U^2 +2as$ whats the U for?

20. saifoo.khan

v = final speed u = initial speed

21. omnomnom

OMG couldnt you write Vi ??? and Vf??

22. omnomnom

And let me guess the S is for time?

23. saifoo.khan

s = distance. duhh.

24. saifoo.khan

And no. We study that here like that.

25. omnomnom

OMG use d for distance please

26. saifoo.khan

$\Large \color{red} {V_i = V_f + 2ad}$

27. omnomnom

thank you

28. saifoo.khan

where are my \$50?

29. omnomnom

i cant give it to you cuz you didnt answer the question :P

30. saifoo.khan

31. omnomnom

but whats the answer? like is it a, b, c, d?

32. saifoo.khan

` solve for d to find out the answer. :p

33. omnomnom

then make the equation less complicated

34. saifoo.khan

35. omnomnom

NO it isnt you know where vi is?? Make d there and then i can answer it :D

36. saifoo.khan

|dw:1349397224874:dw|

37. omnomnom

????? that is sooo confusing you are a bad teacher

38. saifoo.khan

|dw:1349397318428:dw|

39. omnomnom

Nope still dont get it

40. saifoo.khan

Step1: Stop using chat and solve the question first. Step 2: tell me the formula you have.

41. omnomnom

um... $d = \frac{ 1 }{ 2 } (t^2)$

42. saifoo.khan

what other formula do you have?

43. omnomnom

um... $d = vt$

44. saifoo.khan

more..

45. omnomnom

Gosh.. $d = Vi (t) +\frac{ 1 }{ 2 } a (t^2)$

46. saifoo.khan

MORE.

47. omnomnom

OMG IDK ANYMORE!!

48. omnomnom

YOU'RE MESSING WITH ME

49. saifoo.khan

You don't have complete formulas then.

50. omnomnom

YES I DOOOO

51. saifoo.khan

No, im not messing.

52. omnomnom

my teacher gave them to mee

53. saifoo.khan

Oh okay a gut feeling is when you know you should do something but other people (YOU) confuse you or try to make you choose the opposite of your gut but if you still go with your gut you know you were right and stuff but sometimes the gut could be wrong.... I dont think that makes any sense :D

83. saifoo.khan
