Question

IF A MAN IS RUNNING IN A CIRCULAR TRACK OF 14 METER RADIUS AND COVERS 2 AND 1/2 OF THE CIRCLE IN 10 SEC THEN,
A) WHAT IS THE DISPLACEMENT?
B) WHAT IS THE VELOCITY OF THE MAN?​

Answer 1

Explanation:

Your answer is 0,200 m

Stay home and stay safe :-)

Answer 2

Answer:

Displacement=28m

velicity =2.8m/s

Explanation:

i) Since the man is running around circular track and he runs 2 and 1/2 round he reaches just opposite to the starting point.

diaplacement =shortest distance between initial and final point.

so as he is opposite.

displacement =2×radius=2×14=28m

ii) Now we have displacement=28m

total time=10sec.

so,

velocity=displacement/time

v=28/10

v=2.8 m/s

hope it helps!
