Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle \frac{a}{-7} - 7 = 5$ <u />

<u />

<u>Step 2: Solve for </u><em><u>a</u></em>

Addition Property of Equality: $\displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7$
[Simplify] Add: $\displaystyle \frac{a}{-7}= 12$
Multiplication Property of Equality: $\displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7$
[Simplify] Multiply: $\displaystyle a = -84$

<u>Step 3: Check</u>

<em>Plug in a into the original equation to verify it's a solution.</em>

Substitute in <em>a</em>: $\displaystyle \frac{-84}{-7} - 7 = 5$
[Frac] Divide: $\displaystyle 12 - 7 = 5$
Subtract: $\displaystyle 5 = 5$

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.

If a 40,000g cannon ball is 35m above the Earth’s surface, how much potential energy does the cannon ball have?

ELEN [110]

Answer:

Step-by-step explanation:

Remark

You could do this by converting the distance but the much more common way is to use kg and m.

Formula

PE = m * g * h

Givens

m = 40000 grams

m = 40000 grams * 1kg/1000 grams = 40 kg

g = 9.81

h = 35 m

Solution

PE = 40 * 9.81 * 35

PE = 13734 Joules
