Question

A car moves a circular path of radius 20 m in 50 sec with the uniform speed . Find the speed

Answer 1

Answer: 2.512 m/s or. 2.5m/s

Explanation: Radius of circular path = 20 m.

Time = 50 sec

Now , find speed

Speed or V = 2πR/T

= 2 × 3.14 × 20 / 50

= 125.6 / 50

= 2.512 m/s.

OR

= 2.5 m/s.

If you're answer , please give me a comment .

I hope you understand

THANK YOU

Answer 2

Answer:

2.512m/s

Explanation:

speed= distance/time

distance= circumference of the circle= 2$\pi r$/t

radius= 20m

time= 50s

speed=(2×3.14×20)/50

∴speed= 2.512m/s

thank you

hope it helped you
