An object has rotational inertia I. The object,initially at rest, begins to rotate with a constant angularacceleration of magnit
Tresset [83]

Answer:

L = I α t

Explanation:

given,                                          

rotational inertia = I              

initial velocity = ω₀                      

magnitude of acceleration = α      

angular momentum = L          

time = t                              

angular acceleration                                

\alpha = \dfrac{\omega-\omega_0}{t}

\alpha = \dfrac{\omega - 0}{t}

\alpha = \dfrac{\omega}{t}

ω = α t..............(1)

angular momentum                    

L = I ω                    

putting value from equation (1)

L = I α t

A wooden block is sitting on an inclined plane near the bottom. The student gave the block a flick and it moved up the inclined
sladkih [1.3K]

Answer:

The block didn't slide due to balancing of gravitational force with friction force

Explanation:

When the block was given a flick the force provided an acceleration to it and it moved up the inclined plane. when the block reached top it was expected that it would slide back but it didn't this happened because of the frictional force acting on the bottom the block which was balancing the gravitational force component along the plane and this prevented sliding back of the block.

static friction  was balancing mg*sin(theta)

fs = mg*sin(theta)
