Dimensional Analysis and Unit Conversions

The video tutorial explains a two-step dimensional analysis process, converting 100 feet per second to yards per minute. It covers setting up target units, choosing appropriate conversion factors, and performing calculations to achieve the final result of 2,000 yards per minute.

What is the initial unit we are converting from in this dimensional analysis problem?

• Miles per hour

• Meters per second

• Yards per minute

• Feet per second

Which conversion factor is used to convert feet to yards?

• 1 yard = 5 feet

• 1 yard = 2 feet

• 1 yard = 3 feet

• 1 yard = 4 feet

What is the correct conversion factor to change seconds to minutes?

• 1 minute = 45 seconds

• 1 minute = 90 seconds

• 1 minute = 60 seconds

• 1 minute = 30 seconds

Why do we cancel out units before multiplying the numbers?

• To avoid errors in the final result

• To ensure the units match the target

• All of the above

• To simplify the calculation

What is the final result of converting 100 feet per second to yards per minute?

• 2,500 yards per minute

• 2,000 yards per minute

• 1,000 yards per minute

• 1,500 yards per minute
