Answer 1

Answer:Distance in circular motion = Circumference of the circle

As we know, circumference of the circle is denoted by

 

Distance=

 2 × × 20

 

             = 125.7 metre

This means he completed one round in 40 seconds. Thus, he takes 40 seconds to complete one round

Now for 3 minutes= 180 seconds

now taking the ratio,

Thus,

                 

Thus

x=565.7

Thus he covered a distance of 565.7 metre in 3 minutes

for displacement let's divide the covered distance by circumference

=565.7/125.7

=4.500

Now converting this in words

this means he has completed 4 rounds and have completed 1/2 round extra, he is on a point parallel to his starting point

thus he is not on his starting position, thus his displacement is not zero. Drawing a line from starting position to his current position, it will pass through the centre, it is the diameter

Displacement= 2×20

                     = 40 m
