Question
A fly wheel originally at rest is to reach an angular velocity of 36 radian/s in 6 second. The total angle it turns through in the 6 second is
Options
A.54 radian
B.108 radian
C.5 radian
D.216 radian
Solution
ω = ω0 + αt ⇒ 36 = 0 + α × 6 ⇒ α = 6
θ =
× 6 × 36 = 108 radian.
θ =
× 6 × 36 = 108 radian. Create a free account to view solution
