Question

If a cyclist takes 5 turns of a circular park of radius 21m in 1 minute, then its speed in SI units will be_________. *​

Answer 1

Answer:

d = 2πr

=2×22/7×21

=2×22×3

=132 m d= 5×132 = 660 m

t = 1 min

=60 sec

so, speed = 660/60

= 11 m/s

hence, SI UNIT = m/s

the object is in circular motion.
