A disk of mass and radius slips down a rough incline of angle

It’s been a busy summer session and you’ve all been working hard! Wish you the best for the finals and everything else that is due at the end of the summer session.  Here’s a freebie! 🙂

Long Question B: Subpart If you were to draw the FBD of the Block G2   (i.e., System 2 in the diagram below) in phase 1, match the type of forces you will see in the FBD with the direction/location they act in/on. Force Direction Location Normal Reaction [a] [1] Friction [b] [2] Tension Force [c] [3] Weight (i.e., Gravity Force) [d] [4] Select the appropriate answers from the dropdowns.

Two pendulums, ad , with masses and lengths shown are released from rest. Which system has the larger mass moment of inertia about its pivot point? 

Two marbles and with masses and , respectively, are released from rest at a height above the ground. Neglect air resistance. Which of the following statements is true when the two marbles hit the ground?

A solid steel sphere of radius and mass is released from rest and rolls without slipping down an inclined plane as shown below. After traveling a distance , the sphere has a speed .  If a solid sphere of radius is released from rest on the same inclined plane, what will its speed be after rolling a distance ? Hint – think in terms of conservation of energy!

Long Question A: Subpart Complete the relative motion equation relating the velocities of points and (using units of millimeters and seconds).
