Q1. 1.76- block at rest on a ramp of height. While the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 12.0 that has a coefficient of kinetic friction 0.530. Find h such that the block's speed after crossing rough patch is 3.20.
Q2. A wooden rod of negligible mass and length is pivoted about the horizontal axis through its center. A white rat with mass clings to one end of the stick, and the mouse with mass clings to the other end. The system is released from rest with rod horizontal.
