The angular velocity of a wheel increases from 100 to 300 in 10 s. The number of revolutions made during that time is

A

600

B

1500

C

1000

D

2000

Text Solution

Verified by Experts

The correct Answer is:
D
`alpha= (omega- omega_(0))/(t)= (300- 100)/(10)= 20 rp s^(2)`
`theta= omega_(0)t + (1)/(2) alpha t^(2)= 100 xx 10 + (1)/(2) xx 20 xx 100`
= 2000
