Question

The angular speed of a wheel is 88 radian per sec calculate number of revolution made by it in one second

Answer 1

Answer:

14 rev/sec

Explanation:

w=88 rad/sec

2πn=88

.

. . n = 14 rev/sec

Answer 2

Answer:

The wheel makes 14.01 revolutions per second.

Explanation:

Angular speed , ω = 88 rad/s

2π rad / sec = 1 rev/s

∴The number of revolutions per second (RPS) is given by $\frac {\omega}{2 \pi}$

RPS =  $\frac{88}{2\pi}$ ≈ $\frac{88}{2 \times 3.14}$

      = 14.01 rev/sec
