1: A baseball is hit 4 feet above the ground leaves the bat with an initial speed of 98 ft/sec at an angle of 0 45 is caught by an outfielder at a height of 3 feet.

Respuesta :

Answer:

299.36 feet

Explanation:

[tex]To \ find \ the \ distance \ of \ the \ ball \ from \ the \ home \ plate. \\ \\ From \ the \ given \ information:[/tex]

[tex]Height \ h = 4 \ ft[/tex]

[tex]Initial \ speed \ V_o = 98 \ ft/s ec[/tex]

[tex]The \ angle \ \theta = 45^0[/tex]

[tex]Acceleration \ due \ to \ gravity (g)= 32.2 \ ft/s[/tex]

[tex]U_x = V_o \ cos 45 = \dfrac{98}{\sqrt{2}}[/tex]

[tex]U_y = V_o \ sin 45 = \dfrac{98}{\sqrt{2}}[/tex]

So;

[tex]S_y = u_y t - \dfrac{1}{2}gt^2[/tex]

[tex]-1 =\dfrac{98}{\sqrt{2}}t - \dfrac{1}{2}*32*1.85t^2[/tex]

By solving:

[tex]t_1 = 4.32 \ sec[/tex]

Thus;

[tex]horizontal \ distance = U_x t[/tex]

[tex]= \dfrac{98}{\sqrt{2}}\times 4.32[/tex]

[tex]\mathbf{=299.36 \ feet}[/tex]

[tex]\mathbf{Thus \ , the \ distance \ from \ the \ home \ plate \ = \ 299.36 \ feet}[/tex]
