A car is moving at a constant acceleration of 7.0 m/s/s. How fast (velocity) is it going after 4.0 seconds, if it starts from rest.? Show work using ESA format.

Answers

28 m/s is the velocity , when it is going after 4.0 seconds.

What is Acceleration?

When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.

Here, given that,

A car is moving at a constant acceleration of 7.0 m/s/s

Now, we have,

Velocity = acceleration * time

After 4 sec. = 7*4 = 28 m/s

Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.

The group hiked a total of 17.4 miles on the first day. On the second day, the group hiked a distance 12% more than the total distance hiked on the first day. To the nearest tenth of a mile, how many miles did the group hike on the second day?

Answers

On this, you would want to multiply the first by 1.12. So then 17.4 x 1.12= 19.488. when rounded, it equals 19.5 miles.

A car travels 480 miles on 15 gallons of gasoline. How many miles does the car travel per gallon?

Answers

Answer:

32 miles the car travel per gallon.

Step-by-step explanation:

Given : A car travels 480 miles on 15 gallons of gasoline.

To find : How many miles does the car travel per gallon.

Solution : We have given

A car travels on 15 gallons = 480 miles .

A car travels on 1 gallons = $(480)/(15)$ .

A car travels on 1 gallons = 32 miles.

We can say 32 miles the car travel per gallon.

Therefore, 32 miles the car travel per gallon.

you take 480 and divide it by 15, because it says per gallon. so then if the car goes 480 miles with 15 gallons, you have to figure out how to find per gallon. you divide 480/15 and your answer is 32

Write the next three terms of the arithmetic sequence. $(5)/(6)$ , $(2)/(3)$ , $(1)/(2)$ , $(1)/(3)$ , . . .

Answers

The next three terms are: 1/6 , 0 and -1/6

Step-by-step explanation:

Given sequence is:

$(5)/(6) , (2)/(3) ,(1)/(2), (1)/(3) ...$

First of all, we have to find the common difference

$here\na_1 = (5)/(6)\na_2 = (2)/(3)\na_3 = (1)/(2)\na_4 = (1)/(3)\nd = a_2-a_1 = (2)/(3) -(5)/(6) = (4-5)/(6) = -(1)/(6)\nd = a_3 - a_2 = (1)/(2) - (2)/(3) = (3-4)/(6) = =(1)/(6)$
