A hockey puck with a mass of 0.159 kg slides over the ice. The puck initially slides with a speed of 5.45 m/s, but it comes to a rough patch in the ice which slows it down to a speed of 2.75 m/s. How much energy is dissipated as the puck slides over the rough patch? energy dissipated:
A small block of mass m slides to the left on a frictionless, horizontal surface with speed u. Then, the block slides up a rough ramp that has an incline angle of a. The coefficient of kinetic friction between the ramp and box is H. The acceleration due to gravity is g. What is the height h of the block when its speed up the ramp equals cu, where 0 < c < 1? h = CV Final position m Rough surface Initial position Frictionless surface
