A 14.4-g wad of sticky clay is hurled horizontally at a 71-g wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides d=11 m before coming to rest. The coefficient of friction between block and surface is µk=0.56. What is the normal force caused by the ground on the block/blob (again, consider them as one mass)?        2.What is the frictional force on the block/blob?        3. What is the work done by friction on the block/blob?
