A students is trying to determine the maximum rate at which a truck can accelerate to the right without causing the 60kg box sliding off the back of the truck. The coefficient of static friction between the box and the truck bed is 0.52 and the coefficient of the kinetic friction is 0.37. Neglect drag. Answer considering the tuck is accelerating as quickly as possible without causing the box to slide. How many forces are acting on the box? What direction is the friction on the box? Is the friction static or kinetic? What is the magnitude of the frictional force on the box? What is the magnitude of the net force on the box? What is the magnitude of the box's acceleration?
