Six baseball throws are shown below. In each case the baseball is thrown at the same initial speed and from the same height h above the ground. Assume that the effects of air resistance are negligible. Rank these throws according to the speed of the baseball the instant before it hits the ground.

Answer:

The final velocities of all the six balls will be same.

Explanation:

According to law of conservation of energy:

Gain in K.E = Loss in potential energy

   ½ mv^2 = mgh  

Where “m” and “g” are constant. The interchange in energies will occur only with the change in velocity and height. Since, balls are thrown from the same hight with the same initial velocity so, their final velocities will also be same just before striking the ground.

The six balls will reach the ground at the same time, hence the final velocity of the balls will be the same.

During a downward motion of an object, the speed of the object increases as the object moves downwards and becomes maximum before the object hits the ground.

The equation for estimating the final velocity of the six balls is given as;

[tex]v_f = v_i + gt[/tex]

If air resistance is negligible, the six balls will reach the ground at the same time, hence the final velocity of the balls will be the same.
