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

Answers

Answer 1

Answer:

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

Answers

Answer: lol this is what i got

think there was a record of the number of enslaved people who had escaped to seek freedom because probably they wanted to make sure no more slaves would able to escape.  

A inference I you make about why there were more men who sought freedom through escape than women is because the men were probably faster and stronger and the women and that’s why most of them make it out alive.

Some reasons why more enslaved Africans escaped from Queens County than from Suffolk or Kings County was because probably there was a lot of them that outnumber the white peoples.

Explanation:

These advertisements provide information about Sarah and John Ivey as well as a record of the number of slaves who had departed their masters' control in order to find freedom. It is likely that they did this in order to ensure that no other slaves would be able to escape.

What are advertisements?

An advertisement refers to a tool for a promotion that is mainly used to educate people by providing them with information about any existing events or any new product launched in the market.

This advertising can teach us a lot about life in Colonial New York, including the fact that most people survive because men were probably more powerful and faster than women.

What is a church?

In the early Christian era the church were not in the form of buildings or any form of tangible thing or at least not in the sense of what we would consider church buildings today.

The first century Christians were often persecuted and as a result of this harassment the people often met in secret usually in homes. As the influence of Christianity spread, the buildings were established to worship and became what we know today as churches.

There are many images of the church in the Bible, but mostly the three is mentioned: the church as the Body of Christ, the People of God and the Bride of Christ. The Jesus Christ is the head of the church and Christians are the body.

The  goal of the Know-Nothing Party during the mid-1800s is promoting the Catholic Church. Therefore, option (d) is correct.
