Determine the total work they do on the supertanker

1) A 20.0- rock is sliding on a rough, horizontal surface at 8.00 and eventually stops due to friction. The coefficient of kinetic friction between the rock and the surface is 0.200. What average thermal power is produced as the rock stops? 2)Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 2.0×106 , one an angle 18 west of north and the other an angle 18 east of north, as they pull the tanker a distance 0.86 toward the north. What is the total work they do on the supertanker? If anyone can help with these, Thank YOU!!
