Question

Reema moves along a circular path of radius 7 mshe completes 2 full revolutions in 16 seconds find average speed and average velocity of reem

Answer 1

Answer:

Av. Speed is 5.495 m/s, Av. Velocity is 0

Explanation:

Average velocity is zero as velocity is displacement over time and displacement on a circle is zero if you start and end at the same point.

Average speed is distance over time.

Circumference of circle is 2*pi*radius. Assuming pi =3.14

Distance covered in 2 revolutions = 2*(2*pi*7)= 2*43.96 = 87.92 m

Time take = 16 seconds

Speed = 87.92 m/ 16 seconds = 5.495 m/s
