Question

11. A car moves in circular path of radius 20m in 50s with uniform speed. Find speed.​

Answer 1

Answer:

hey Mate here is ur ans

speed = distance/time

s= d/t = 2πr/t

s= 2π(20)/50

s= 40π/50

s= 0.8π

hope it help u

Answer 2

Answer:

the circumfrence=2πr

=)2×20×21/7

=)40×21/7

=)840/7

=)120

the distance covered in 50s is 120 m

now speed=d/t

so speed = 120/50

=)12/5

=)2.4 m s -¹

the car is at uniform speed of 2.4 m s-¹
