Two flat stone blocks of masses 100kg each are stacked on top of one another on the back of a truck. The coefficient of static friction between the bottom block and the truck is 0.8 and between the two blocks is 0.7. (Describe how you get the answers per question!) a) What is the maximum acceleration the truck can have such that neither of the blocks slide off ? b) If the truck accelerates from rest at this maximum acceleration for 6 seconds, how much more energy will the truck's engine need to output compared to if the stone blo cks were not on the truck?

a) What is the maximum acceleration the truck can have such that neither of the blocks slide off ?
b) If the truck accelerates from rest at this maximum acceleration for 6 seconds, how much more energy will the truck's engine need to output compared to if the stone blo cks were not on the truck?
c) What is the maximum speed that the truck can drive around a curve of minimum curvature radius 100m without either of the blocks sliding off ?
d) What is the maximum slope that the truck can drive up at constant speed without either of the blocks sliding off?
