Answer:
=>By the work energy relation:-
=>W = ∆KE
=>Ff.s = 1/2(M+m)v^2
=>µk x N x s = 1/2(M+m)v^2
=>µk x (M+m) x g x s = 1/2(M+m)v^2
=>v = √[2µkgs]
=>v = √[2 x 0.82 x 9.8 x 10.6]
=>v = 13.05 m/s
By the law of momentum conservation:-
=>Mu = (M+m)v
=>9230u = (9230+1250) x 13.05
=>u = 14.82 m/s

The width of border is 1.5 feet
<h3><u>
Solution:</u></h3>
Given that small garden measures 9 ft by 13 ft
A uniform border around the garden increases the total area to 192 ft square
To find: width of border
Let the width of border be "x"
Then the new measures of garden are (9 + 2x) feet and (13 + 2x) feet
The total area of garden = 192 square feet
<em><u>Let us solve the above equation by quadratic formula</u></em>
Using the above formula,
For 
, we have a = 4 ; b = 44 ; c = -75
Substituting the values of a = 4 ; b = 44 ; c = -75 in above quadratic formula we get,
Since "x" cannot be negative,
we get x = 1.5
Thus width of border is 1.5 feet
Oma made a mistake in step B, because she should have divided both sides by b instead of just moving it to the other side. The real next step would look like:
(2A)/b=h
Point L is the midpoint
The midpoint is halfway between the two points. In this case, Point F and Point B are 10 units away from each other. The midpoint is the distance between the points (10) divided by 2.
