Farmer's Motion and Displacement Concepts

The video tutorial explains how a farmer moves along the boundary of a square field, completing one round in 40 seconds. It calculates the speed of the farmer as 1 meter per second and explores how to find the magnitude of displacement after 2 minutes and 20 seconds using the Pythagorean theorem. The tutorial concludes with a call to subscribe for more educational content.

What is the shape of the field along which the farmer moves?

• Triangle

• Rectangle

• Square

• Circle

How long does it take for the farmer to complete one round of the field?

• 50 seconds

• 40 seconds

• 30 seconds

• 20 seconds

What is the speed of the farmer as he moves along the boundary?

• 1.5 meters per second

• 0.5 meters per second

What is the final position of the farmer after traveling 140 meters?

• At the starting point

• 10 meters from the start

• 20 meters from the start

• 30 meters from the start

Which theorem is used to calculate the displacement of the farmer?

• Fermat's theorem

• Euclid's theorem

• Thales' theorem

• Pythagorean theorem

What is the magnitude of the farmer's displacement after 2 minutes and 20 seconds?

• 20 meters

• 10√2 meters
