What’s the force of a pitching machine on a baseball?
baseballs pitched by a machine have a horizontal velocity of 30 meters/second. the machine accelerates the baseball from 0 meters/second to 30 meters/second in 0.5 seconds. if a baseball has a mass of 0.15 kilograms, the force the machine exerts is newtons.

F = 9 N

Explanation:

As we know that the acceleration of ball is given as rate of change in velocity of the object

so here we will have

here we know that

now we will have

now in order to find the force we will use Newton's II law which is given as

now by above formula we have

Force, F = 9 N

Explanation:

Initial velocity of the baseball, u = 0 m/s

Final velocity of the baseball, v = 30 m/s

Time taken, t = 0.5 s

Mass of the baseball, m = 0.15 kg

We know that the force of a pitching machine on a baseball is given by using second law of motion. It is given by :

F = 9 N

So, the force of 9 N is pitching machine exert on a baseball. Hence, this is the required solution.
