m M A small block of mass m = 720. g is compressing a spring of spring constant 323 N/m by 26.1 cm. When released, it slides 176 cm across a rough surface (coefficient of kinetic friction = 0.210) and collides with a thin rod of length d= 144 cm and mass M = 790. g that is free to rotate about its top point. If the block sticks to the rod, what is the rod's angular speed just after collision?
