A wheel has angular acceleration of 3.0 rad/sec² and an initial angular speed of 2.00 rad/sec. In a time of 2 sec it has rotated through an angle (in radian) of
Options
(a) 10
(b) 2
(c) 4
(d) 6
Correct Answer:
10
Explanation:
Given: Angular acceleration, α = 3 rad/sec², Initial angular velocity ωᵢ = 2 rad/sec, Time t = 2 sec
Using, θ = ωᵢt + (1/2) αt²
.·. θ = 2 x 2 + (1/2) x 3 x 4 = 4 + 6 = 10 radian
