Week 5
•Projectile Motion Discussion
Solve problem 5.5.33
• Consider the schematic in Figure 4.1 and imagine
that the block was being lowered into a pool of fluid,
and is experiencing a friction force of Fliquid directed
vertically up.
• Draw a FBD for m2.
• Assume that the block is falling with some
acceleration az
• Apply Newton's Second Law in the z direction to
derive an equation for the block's acceleration.
