15. ### Throws a stone horizontally with a velocity of 20ms-1

Thank you so much for the help...
16. ### Throws a stone horizontally with a velocity of 20ms-1

thanks a lot...
17. ### Throws a stone horizontally with a velocity of 20ms-1

so i got all correct? even the second?
18. ### Throws a stone horizontally with a velocity of 20ms-1

how about the number 2? this is my solution: s = 1/2(u+v)t = 18.75 m
19. ### Throws a stone horizontally with a velocity of 20ms-1

tell me if i got 1b correct. i use your formula, s = 20 m/s (10.68 s) s = 213.6 m... is it right? thanks a lot....
20. ### Throws a stone horizontally with a velocity of 20ms-1

is this correct for 1a. -560 = -1/2 (9.81) t^2 t = 10.68 im not sure if that s correct

22. ### Throws a stone horizontally with a velocity of 20ms-1

so t = 10.68... by the way where did you get 500? is it 560?

25. ### Throws a stone horizontally with a velocity of 20ms-1

i didnt get your equation because of so much symbols, sorry...
