Step-by-step explanation:
E = m/2g(v²-u²)
2g×E = 2g×m/2g(v²-u²)
2Eg = m(v²-u²)
2Eg = mv² - mu²
mu²= mv² -2Eg
mu²/m = mv² -2Eg /m
u²= v² -2Eg
u = √v²-√2Eg
Answer:
6
Step-by-step explanation:
Given in the question that,
length of the diagonal of a square = 6√2
As we know that a square have all lengths equal in size and lengths are perpendicular to each other so to solve this question we will use pythagorus theorem
hypotenuse² = base² + height²
here,
hypotenuse is the diagonal of the square
base and height side length of the square
Plug value in the formula
6√2² = l² + l²
36(2) = 2l²
72 = 2l²
l² = 72/2
l² = 36
take square root on both sides of the equation
l = √36
<h3>l = 6</h3>
Answer: b = 2a
Step-by-step explanation:
<u>Original equation</u>
a = (1/2) b
<u>Multiply 2 on both sides</u>
a * 2 = (1/2) b * 2

42 x 28 = (40 + 2) x (20 + 8) = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8
= 800 + 320 + 40 + 16
