You give the book's a light push and it slides straight across the table with constant speed. 4.1.1 Use Newton's laws of motion to explain the effect of the light push on the book state of rest. (2) 4.1.2 Draw a labelled free body diagram of all the forces that acts on the book during its uniform motion. (2) 4.1.3 Based on the motion of the book is there friction between the surfaces of the book and table? Explain your answer. 4.1.4 Predict what might happen to the motion of the book if external force acts on it. Explain your prediction(s). 4.2 The gravitational force exerted by the Earth on the Moon holds the Moon in an orbit around the Earth. Assume that the orbit of the Moon is perfectly circular. 4.2.1 If the force of gravity between the Earth and Moon suddenly disappeared, what would the path be that the Moon follows? Explain your answer. 4.2.2 If the Earth's mass is $ 5.98 \times 10^{24} \mathrm{~kg} $ and the Moon's mass is $ 7.36 \times 10^{22} \mathrm{~kg} $ and the average distance between them is $ 3.84 \times 10^{5} \mathrm{~km} $, determine the acceleration of the Moon towards the Earth.
