a) Calculate the force of gravity between two apples each with a mass of 0.175 kg, with their centres of mass 0.050 m apart.

b)16.A 50 kg person is standing on a bathroom scale inside an elevator. The scale is calibrated in Newtons. What is the reading on the scale when the elevator is accelerating down at 1.8 m/s2 ?

c) Two boxes sit side by side on the floor. The larger box (box 1) has a mass of 25 kg and sits to the left. The smaller box (box 2) has a mass of 10 kg and sits to the right. A person pushes on the larger box with a horizontal force to the right. The coefficient of static friction on both trunks is 0.45. Determine the magnitude of the maximum force (Fa) the person can exert without moving either box (remember Fa = Fsmax). Calculate the force (F1on2) the larger box exerts on the smaller box.

d) A string is tied from a 5.00 kg object on a table to a 2.00 kg object hanging over the edge of the table by a frictionless pulley with a massless string. The coefficient of kinetic friction between the 5.0 kg object and the table is 0.250. Calculate the acceleration of each of the objects (they will be the same).
