Question

If a rigid body a point rotates 60 degrees in 6minutes the angular velocity of the body is-

Answer 1

angular velocity of the body is π/1080 rad/s²

explanation : we know,

angular velocity of a body is the rate of change of angular position with respect to time.

i.e., ω = ∆θ/∆t

here , change in angular position, ∆θ= 60° = 60°/360° × 2π rad = π/3 rad

time interval , ∆t = 6 min = 6 × 60 = 360 sec

now angular velocity of the body, ω = (π/3)/360 = π/(360 × 3) = π/1080 rad/s²

Answer 2

$\huge\bold\purple{Answer:-}$

If a rigid body a point rotates 60 degree in 6 minutes the angular velocity of the body is [π/1080] rad/sec or [π/(6*180)] rad/sec
