In physics, kinetic energy is the energy of an object in motion. Kinetic energy, K, measured in joules (J), is

Kryger [21]

Answer:

$m = \frac{2k}{v^{2} }$

Step-by-step explanation:

$k = \frac{1}{2} mv ^{2}$

$v ^{2} m = 2k$

$m = \frac{2k}{v ^{2} }$

The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.

Because the 2 sides are the same the 2 bottom angles are also the same.

This means that 9x +3 = 84

Now we can solve for x:

9x +3 = 84

Subtract 3 from each side:

9x = 91

Divide both sides by 9:

x = 81 / 9

x = 9

Paula walks 1/12 mile in 5/3 minutes. What rate is equivalent to the rate she walked?

mel-nik [20]

The rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute

<h3>Calculating Rate </h3>

From the question, we are to determine the rate which is equivalent to the rate Paula walked

Using the formula,

$Rate = \frac{Distance}{Time}$

From the given information,

Distance = 1/12 mile

Time = 5/3 minutes

Putting the parameters into the formula, we get

$Rate =\frac{\frac{1}{12} }{\frac{5}{3} }$

$Rate = \frac{1}{12} \div \frac{5}{3}$

$Rate = \frac{1}{12} \times \frac{3}{5}$

$Rate = \frac{3}{60}$

$Rate = \frac{1}{20}$ mile/minute

Hence, the rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
