... A block of mass M is cemented to a circular platform at a distance b from its center. The platform can rotate, without friction, about a vertical axle through its center with a moment of inertia, Ip. If a bullet of mass m, moving horizontally with velocity of magnitude vB as shown, strikes and imbe ...

... 5. Note any Newton’s third law force pairs present in these two freebody diagrams (if any) by putting the same number of lines through the force vectors on the diagrams. For example, these two vectors are marked as being a pair: Also, make a list of those force pairs here. Verify that every force pa ...

Question Title
... Justification: The friction force is the same at all times when the block is sliding. The block experiences the constant friction force of: f fric k FN k mg In the equation above, uk, m and g are all constant with respect to time so the friction force is constant at all times. Recall that in ...
