A solid wooden cylinder rolls two different inclined planes of the same hight but with different angle of inclination. Will it reach the bottom with the same speed in each case? Will it take longer to roll down one incline the other? Explain your answer

```							From this equation, one can see that if the angle ? is increases, the value of d will decrease, together with the increase in angular and linear acceleration.Therefore the wooden cylinder on inclined plane having larger angle of inclination will reach the ground earlier than the wooden cylinder on the inclined plane with smaller angle of inclination and the cylinder will have different speed when it reaches the bottom of the inclined plane.The dashed line in the figure shows that changing the angle of inclination, while keeping the height constant changes the distance d to be traversed by the cylinder.The distance d can be related to the height of the inclined plane as:It can be seen from this equation that the angular acceleration is directly proportional to the sine of the angle of the inclination of the inclined plane.It is important to note that if the height is kept constant and the angle of inclination is changed, then the distance d (refer figure below and the dotted line) will also change, and is important to determine the time taken by the wooden cylinder to reach the bottom.It can be seen from this equation that the linear acceleration is directly proportional to the sine of the angle of the inclination of the inclined planeThe angular acceleration of the wooden block can be calculated using relation a = a/r, , asa = a / RAlso, applying Newton’s third law of motion for the forces acting along the length of the inclined plane,Here f is the magnitude of force of friction.The diagram showing the forces acting on the wooden cylinder on inclined plane is shown below: = Ia, , one can deduce the effect of angle of inclination on the motion of cylinders.tAssume that only friction between the wooden cylinder and the inclined plane is responsible for producing the torque in the wooden cylinder, then using
