You say that there is uniform acceleration so:
vf-vi=at (final velocity minus initial velocity is equal to acceleration times time)
We know vf, vi, and t so we can solve for acceleration:
24-12=a10
12=10a
a=1.2
That is the acceleration, we will need to integrate with respect to time twice...
v=⌠a dt
v=at+vi , we know a=1.2m/s^2 and vi=12m/s
v=1.2t+12,
x=⌠1.2t+12 dt
x=1.2t^2/2+12t+xo, we can just let xo=0 for this problem...
x(t)=0.6t^2+12t
Now we know that this acceleration lasts for 10 seconds so the distance traveled in that time is:
x(10)=0.6(10^2)+12(10)
x(10)=60+120
x(10)=180 meters
Answer:
(0, 50) (25, 57.5) (50, 122.5) (75, 195) (100, 275)
Step-by-step explanation:
We know that he earns 30% percent of the money made on sales, plus $50 a week. We know that he starts off with 50, because that's how much he made by working that week. To figure out how much money he made off of each one, we have to calculate 30% of the sale, and add that to the total amount of money he has made up to that point. I hope this helps :)
Answer:
13/21
Step-by-step explanation:
The breadth of rectangle is 14 cm
The perimeter of rectangle is 65 cm
<em><u>Solution:</u></em>
Given that,
Area of rectangle = 259 square centimeter
Length of rectangle = 18.5 cm
<em><u>The area of rectangle is given by formula:</u></em>
<h3><u>Find the breadth:</u></h3>
Substitute the given values in above formula:
Thus breadth is 14 cm
<h3><u>Find the perimeter:</u></h3>
The perimeter of rectangle is given by formula:
Substitute the given values in above formula:
Thus perimeter of rectangle is 65 cm
