Question

An object moving uniformly in a circular path of radius 12 cm completes 7 revaluations in 100 s. what is the angular speed,and the linear speed of the motion?

Answer 1

angular speed of an object moving uniformal in circular path is 0.4396

Answer 2

Answer:5.27×10^-2m/s

Explanation:

R=12cm (convert the cm to m)

=12×10^-2

No of revolutions(n)=7

Time=100s

Angular speed(ω)= θ/t. (θ=2πn, circumference×no of revolutions)

=2×3.14×7/100

=0.44

V=ω×R. (R=12×10^-2)

=0.44×12×10^-2

=5.27×10^-2

Hope it helps you out!
