Angular velocity of a particle is expressed as ‘ω’. The change in angular displacement is expressed as ‘dθ’.

The time taken for the angular displacement is t. Angular velocity of a particle is the rate of change of

angular displacement with respect to the time. This makes the angular velocity formula expressed as ω = dθ /

dt.

seconds.

Given is the path of the bock is θ = 3 t

ω = dθ/dt = 6 t - 12

For t = 8 seconds, the angular displacement of the block is

ω = 6 * 8 - 12 = 48 - 12 = 36 rad/seconds.

seconds.

Given is the path of the bock is θ = t

ω = dθ/dt = 3 t

For t = 6 seconds the angular displacement of the block is

ω = (3 * 36)-(4 * 6) = 108-24 = 84 rad/seconds.
