A block of mass m1 = 2.30 kg is placed in front of a block of mass m2 = 5.20 kg, as shown in the figure. The coefficient of static friction between and m2 is 0.65, and there is negligible friction between the larger block and the tabletop.
a) What forces are acting on m1?
b) What is the minimum external force F that can be applied to m2 so that m1 does not fall?
c) What is the contact force between m1 and m2?
d) What is the net force acting on m2 when the force found in part (b) is applied?
