What’s the force of a pitching machine on a baseball?

The Machine exerts a force of 9N.

Explanation:

Initial velocity (u) = 0 m/s

Final velocity (v) = 30 m/s

Time (t) = 0.5 s

Acceleration (a) = (v-u)/t

= (30-0)/0.5 m/s²

= 30/0.5 m/s²

= 60 m/s²

Mass = 0.15 kg

Force = Mass*Acceleration

= 0.15*60 N

= 9 N

Explanation:

i would say b. research typically uses a variety of sources

bro these r easy u may have to do them urself bro. lol jk the answer is two for nimber one, and for question number two sahel boi xd have fun get rekt m8
