The Wheels of automobiles are rotating with an angular velocity of 14

1.	The Wheels of automobiles are rotating with an angular velocity of 14 rev/second which is a reduced to 38 rad/sec in 5 seconds when breaks are applied. its angular acceleration is
Answer» :INITIAL angular velocity = 14 rev/sFinal angular velocity = 38 rev/sTime interval = 5sWe have to find angular acceleration of the wheel★ Angular acceleration is measured as the RATE of change of angular velocity of object.α = ω₂ - ω₁ / tα DENOTES angular accelerationω₂ denotes final angular velocityω₁ denotes initial angular velocityt denotes timeIt is an axial vector quantity having both MAGNITUDE as well as direction.Angular acceleration is a rotational analogue of linear acceleration.SI unit : rad/s²By substituting the given values;➝ α = 38 - 14 / 5➝ α = 24/5➝ α = 4.8 rad/s²
