Question

The acceleration of an object due to gravity is 32 feet per second squared. What is acceleration due to gravity in inches per second squared?
3/8 inches per second squared
2 2/3inches per second squared
384 inches per second squared
1,024 inches per second squared

Answer 1

For this case we know that by definition, the conversion of foot to inches is given by:

$1 foot = 12 inches.$

Applying the conversion to the given expression we have:

$(32 \frac {feet} {s ^ 2}) 12 \frac {inches} {feet} = 384 \frac {inches} {s ^ 2}$

Answer:

The acceleration due to gravity in inches per second squared is:

$384 \frac {inches} {s ^ 2}$

Option 3

Answer 2

For each foot there are 12 inches  so we multiply by 12

32*12 = 384 inches
