1.	A horse running along a circular track of radius 10 m completes one round in 50s. What is the distance covered and displacement?
Answer» above QUESTION , the following information is given - A horse running along a circular track of radius 10 m COMPLETES one round in 50s. We have to find the distance covered and the displacement of the horse.Solution - First let me DEFINE distance and displacement .Distance refers to the total length of the path covered between two points , whereas displacement is the shortest distance between the points . Here , .The horse runs around in a circle and completes one round , returning to the same point . As it returns to the initial point , the displacement becomes zero . Now ,The required distance travelled by the hose is the CIRCUMFERENCE of the path travelled .We have the following information - The radius of the track is 10 m.We know that - Circumference => 2. π r => 20 π metres .=> 20 × 3.14 metres=> 61.8 m So , hence the distance travelled by the horse is 61.8 metres . NOTE that the time given is superfluous here .
