A toy cart of mass m1 moves on frictionless wheels as it is pulled by a string under tension T. A block of mass m2 rests on top of the cart. The coefficient of static friction between the cart and the block is μ. Find the maximum tension T that will not cause the block to slide on the cart if the cart rolls on
(a) A horizontal surface;
(b) Up a ramp of angle θ above the horizontal. In both cases, the string is parallel to the surface on which the cart rolls.
