A wheel rotates with a constasnt acceleration of `2.0rad/s^2`. If the wheel starts from rest, how many evolutions wil it make in the first 10 senconds?

A

8

B

16

C

24

D

32

Text Solution

Verified by Experts

The correct Answer is:
B
`theta=omega_(0)t+(1)/(2)alphat^(2)impliestheta=100` rad
`therefore` Number of revolutions = `(100)/(2pi)=16` (approx).
