You toss a ball from your window 8m above the groun. When the ball leaves your hand, ut is moving at 10m/s at an angle of 20 degree below the horizontal. How far horizontally from your window will the ball hit the ground? Ignore air resistance. Plz answer it fast . It's my humble request.

Answer 1

Vo = 10m/s[20o] S. of E.
Xo = 10*Cos20 = 9.4 m/s.

h = 0.5g*Tf^2 = 8 m.
4.9Tf^2 = 8, Tf = 1.28 s. - Fall time.

Dx = Xo*Tf = 9.4m/s * 1.28s = 12 m.

Answer 2

Mery assignment MN ye question h plz koi solve kr do

Answer 3

Vix=Vicos20°=
Viy=Visin20°
8=Viyt + 1/2gt^2
t=-viy/4g
X=Vix t + 1/2 a t^2. |a=0|
X=Vix t

Answer 4

Vix=Vicos20°=
Viy=Visin20°
8= 1/2gt^2
t^2=16g
X=Vix t + 1/2 a t^2. |a=0|
X=Vix t
