Question

Angular displacement 0 of a flywheel varies with
time as 0=at + 2bt, then angular velocity is given
by
(1) a+2bt
(2) a + 4bt
(3) a-2bt
(4) zero​

Answer 1

Answer:

answer will be 0

Explanation:

s=0

0=at+2bt

-2bt-at=0

-a (2t+t)=0

-a×3t=0

-3ta=0

a=0

v^2=u^2+2as

v^2=0^2+2 (0)(0)

v^2=0 angular velocity is 0
