If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s, what is the acceleration of the objec
SVETLANKA909090 [29]

Answer

Find out the what is the acceleration of the object .

To prove

Formula

Acceleration = \frac{Final\ velocity - Intial\ velocity}{Time }

Where

t = the time in which the change occurs

As given

If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .

Final velocity = 98 m/s  

Intial velocity = 65 m/s

Time = 12 s

Put in the formula

Acceleration = \frac{98 - 65}{12}

Acceleration = \frac{33}{12}

Acceleration = 2 .75 m/s ²

Option (A) is correct .

Sara can type 90 words in 4 minutes. About how
LiRa [457]

Answer:

225 words

Step-by-step explanation:

In order to find the answer to this question we have to find how many words she writes in 1 minute. To do this you need to divide 90 words by 4 minutes:

(90)/4 = 22.5 words/minute

Now that the words per minute is found, we can multiply it by the 10 minutes to find how many words she can write in 10 minutes:

(22.5)(10) = 225

Therefore, Sara can type about 225 words in 10 minutes.
