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

Answer 1

Answer:

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.

10 Points! How do you calculate the volume of a 3D figure? Example(s)?

Answers

There is not really a rule to figuring out this question.There are kinda multiple ways to determine the volume of a 3D object. It really depends on what 3D object you are trying to find the volume for. But i can give you and example. Say you have a 3 dementional cube and you need to find the volume of that cube. You would take the bottom square of the cube and fine the area like you would any other square. But since this is a cube you have height to worrie about. So you will take the area you got for the bottom square and times that by the height. You will then have your answer. And if you are dealing with a cylinder same thing goes except with circle. Find the area of the bottom circle then times that by the area. Hope this helped sorry for taking so long.

Don saves $1 the first week, 2$ the second week, $3 the third week, and $4 the fourth week. If he continues in this way, how many weeks will it take before Don has saved at least $50?Please show me the simplest and quickest way to solve this problem. EXPLAIN YOUR STEPS THOROUGHLY!!

Answers

This forms an arithmetic sequence, where the first term = 1, common difference = 1, and number of terms = n.

The formula for the sum of an arithmetic sequence is

$S_(n) = (1)/(2)n(2a + (n - 1)d)$

Where a = the first term and d = the common difference.

We want the sum to be at least $50, so
$50 \leq (1)/(2)n(2a + (n - 1)d)$

Substituting in a and d
$50 \leq (1)/(2)n(2(1) + (n - 1)(1))$

Rearranging
$50 \leq (1)/(2)n(2 + (n - 1))$
$50 \leq (1)/(2)n(1 + n)$
$100 \leq n(1 + n)$
$100 \leq n^2 + n$
$0 \leq n^2 + n - 100$

$\text{Let } n^2 + n -100 = 0$
$n = (-1 \pm √(1-4(1)(-100)))/(2)$
$n = (-1 \pm √(401))/(2)$
$n \geq 0 \implies n = (-1 + √(401))/(2)$
$n \approx 9.51$

So it will take 9.51 weeks, or 10 weeks to the nearest week.
