There is a 5kg box sitting on top of a 10kg box. The static friction between them is .5. What is the maximum tension that can be placed on the bottom box without causing the 5kg box to slip. The surface is flat.
max friction= .5*5g
max acceleration= maxfriction/mass
max tension= 15kg*accmax= 15(.5*5g)/5
