Nonuniform cylindrical object. In the figure, a cylindrical object of mass M and radius R rolls smoothly from rest down a ramp and onto a horizontal section. From there it rolls off the ramp and onto the floor, landing a horizontal distance d = 0.504 m from the end of the ramp. The initial height of the object is H = 0.88 m; the end of the ramp is at height h = 0.13 m. The object consists of an...

1. A rigid object with moment of inertia 0.4 kg mº is spinning with angular speed of 0.2 rad/s around a fixed axis. A constant torque of 0.6 Nm is applied that increases the rotation speed of the object (no other force is present). (i) Calculate the angular acceleration of the object. (ii) Calculate the angular speed of the object at t = 4 s. (iii) Calculate the angle spanned by the object from 0 s to 4 s.

Rotational Energy 1. a) An object is rolling without slipping towards an inclined ramp. The object has a radius of 0.13 m, a mass of 1.2 kg, and is traveling with a speed of 1.5 m/s. When the object travels up the ramp, it reaches a maximum height of .43 m before it stops and then begins to roll back down the ramp. What is the moment of inertia of the object?
a) Draw fully labelled free body and extended free body diagrams for the object. b) Explain what causes the object t...
