An object has rotational inertia i. the object, initially at rest, begins to rotate with a constant angularacceleration of magnitude alpha. what isthe magnitude of the angular momentum l ofthe object after time t?
express your answer in terms ofi, alpha, andt.
l =

L = I α t

Explanation:

given,                                          

rotational inertia = I              

initial velocity = ω₀                      

magnitude of acceleration = α      

angular momentum = L          

time = t                              

angular acceleration                                

ω = α t..............(1)

angular momentum                    

L = I ω                    

putting value from equation (1)

L = I α t
