6. In baseball, a fastball takes about 1/2 second to reach the plate. Assuming that such a pitch is thrown horizontally, compare

Answer:

<em>The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second</em>

Explanation:

<u>Horizontal Launch </u>

When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled exclusively by gravity until it eventually hits the ground.

To calculate the vertical distance (y) traveled by the object in terms of the time (t) we use:

$\displaystyle y=\frac{g.t^2}{2}$

The fastball is thrown horizontally. The distance the ball falls in t=1/4 seconds = 0.25 seconds, is:

$\displaystyle y_1=\frac{9.8*0.25^2}{2}$

$\displaystyle y_1=0.30625\ m$

The distance the ball falls in t=1/2 seconds = 0.5 seconds is:

$\displaystyle y_2=\frac{9.8*0.5^2}{2}$

$\displaystyle y_2=1.225\ m$

The distance it falls in the second 1/4 second is:

$y_2-y_1=1.225\ m-0.30625\ m$

$y_2-y_1=0.91875\ m$

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

Consider the model above. It represents the electrical force. As r increases, the attractive force decreases. How would this mod

aivan3 [116]

Answer:

As we keep on increasing the radius the value of the gravitation force of attraction decreases and as we decrease the radius the gravitation force increases.

Explanation:

Like the coulombs law of electrostatics, the law of gravitation also depends inversely on the square of the value of r. Therefore, as we keep on increasing the value of r the value of the gravitation force decreases and as we decrease the value of the r the value of gravitation force increases.

Gravitation Force= $\frac{Gm_{1}m_{2} }{r^{2}}$
