Question

Help urgent please, some physics some math

Answer 1

@Abhishek619 or anyone

Answer 2

@Loser66 thanks for having a look
i have no clue where to start yet

Answer 3

May be I cannot help. Anyway, I am trying

Answer 4

ty i have no hope i can do it myself alone :(

Answer 5

y=h+s(cotb)
use equations of motion. y=(Vo sin (alpha) (t)+(1/2)(-g)t^2
and also, (Vo cos (alpha)) (t)=d+s
get s from there.

Answer 6

so, you can get the time the stone travels.

Answer 7

im trying to digest the equation both..

Answer 8

agree with Abhishek619

Answer 9

i get Loser66's vertical component equations

Answer 10

to me, after getting the time t, apply to distance equation from horizontal line. It says
x = x_0 + V_0x t + 1/2 at^2 , where x_0=0, a =0 and X = d+s

Answer 11

and V_0x = V_0 cos 49

Answer 12

how to get time, i didnt get Abhishek's y = h+scot(b) equation sorry :(

Answer 13

hehehe, I go backward.

Answer 14

vertical :

y = 20sin(49) - 5 t^2

Answer 15

horizontal :
x = 20cos(49)*t

Answer 16

wher to go from here

Answer 17

what is x?
x is the horizontal distance which the particle has covered.
what is that? it is the sum of h and s.
do you agree?

Answer 18

^^ yes...

x = h+s when the stone hits the incline

Answer 19

sorry,

x = d+s

Answer 20

oh sorry!
my bad!
good going.
t=d+s/ (Vo cos (alpha))
substitute t in
y=(Vo sin (alpha) (t)+(1/2)(-g)t^2
you get a quadratic equation in terms of 's'. now solve that quadratic equation and get the value of s.

Answer 21

oww it looks easy, ima try

Answer 22

t = (15+s)/(20 cos(49))

y = 20sin(49) - 5 t^2

Answer 23

but 2 equaitons with 3 unknowns : t, y, s ?

Answer 24

y=h+ s(tan (beta))

Answer 25

ugh im real dumb

Answer 26

t = (15+s)/(20 cos(49))

y = 20sin(49) - 5 t^2

y= 6+ s(tan (30))

Answer 27

3 equations , 3 unknowns
anbody can solve lol
you're awesome thanks a lot !!!!!

Answer 28

lol yea.
you're welcome!!
