1.) The Force Exerted on the Moon (Figure 1)shows the Earth, Moon, and Sun (not to scale) in their relative positions at the time when the Moon is in its third-quarter phase. Though few people realize it, the force exerted on the Moon by the Sun is actually greater than the force exerted on the Moon by the Earth. In fact, the force exerted on the Moon by the Sun has a magnitude of FsM = 4.34 x 10^20 N, whereas the force exerted bythe Earth has a magnitude of onlyFeM = 1.98 X 10^20 N. These forces are indicated toscale in the figure.a) Find the direction of the net force acting on the moon.b) Find the magnitude of the net force acting on the moonc) Given that the mass of the Moon is Mm = 7.35 10^22 kg, find the magnitude of its acceleration at the time of the third-quarter phase. 2.) A 6.4 kg bowling ball and a 7.1 kg bowling hall rest on a rack of 0.83 m apart.a) What was the force of gravity exerted on each of the balls by the other ball?b) At what separation is the force of gravity between the balls equal to 2.3 x 10^-9 N?3.) You pull upward on a stuffed suitcase with a force of 150 N, and it accelerates upward at 0.750 m/s^2 a) What is the mass of the suitcase?b) What is the weight of the suitcase? 4.) At the bow of a ship on a stormy sea, a crewman conducts an experiment by standing on a bathroom scale. In calm waters, the scale reads 179 lb.During the storm, the crewman finds a maximum reading of 220 lb and a minimum reading of 137Ib.a) Find the magnitude of the maximum upward acceleration experienced by the crewmanb) Find the magnitude of the maximum downward acceleration experienced by the crewman.
