Example 6 6 A block of mass m 1 kg moving on a horizontal surface with speed v 2 ms enters a rough patch ranging from x 0 10 m to x 2 01 m The retarding force F on the block in this range is inversely proportional to x over this range k F for 0 1 x 2 01 m 0 for x 0 1m and x 2 01 m where k 0 5 J What is the final kinetic energy and speed u of the block as it crosses this patch V
