a ball thrown horizontally from the top of a tall cliff three seconds later the ball has fallen a vertical distance ofa.) 20 mb.) 30 m c.) 45 md.) depends on the horizontal speed of the ball

Respuesta :

Given data

The duration of the ball traveled is t = 3 s

The expression for the vertical distance is given as:

[tex]S=\frac{1}{2}gt^2[/tex]

The acceleration due to gravity is taken as g.

Substitute the value in the above equation.

[tex]\begin{gathered} S=\frac{1}{2}\times10m/s^2\times(3s)^2 \\ S=45\text{ m} \end{gathered}[/tex]

Thus, the vertical distance is 45 m.

Thus, the correct option is (c).
