Question

The acceleration of an object due to gravity is 32 feet per second. What is acceleration due to gravity in inches per second?

Answer 1

Answer:

384 inches per second.

Step-by-step explanation:

So acceleration of an object due to gravity is 32 feet per second.

And we want to find the acceleration in inches per second.

First, 32 feet per second is the same as:

$\frac{32\text{ feet}}{\text{second}}$

Use dimensional analysis. We know that there is 12 inches in a feet. So, multiply by 12in/feet:

$\frac{32\text{ feet}}{\text{second}}\cdot\frac{12\text{ inches}}{\text{feet}}$

The "feet" cancel. Thus:

$=\frac{32\cdot 12\text{ inches}}{\text{second}}$

Multiply:

$=\frac{384\text{ inches}}{\text{second}}$

So, our answer is 384 inches per second :)
