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. use f = ma, where .

9N

Explanation: Well first I used the acceleration formula, Change in velocity over change in time. Which was 30/0.5 and got 60. Then I plugged it into F= ma giving me F= (60)(0.15) which equals 9. Please let me know if I'm correct it's been a while

Force, F = 9 N                                                                                                                          

Explanation:

It is given that,

Initial speed of the machine, u = 0

Final speed of the machine, v = 30 m/s

Time taken, t = 0.5 s

Mass of the baseball, m = 0.15 kg

Let F is the force of a pitching machine on a baseball. It can be calculated using the second law of motion. The mathematical form of second law of motion is given by :

F = 9 newton

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

the answer is 12 as i may remember
