One possible means of achieving space flight is to place a perfectly reflecting aluminized sheet into Earth’s orbit and to use the light from the Sun to push this solar sail. Suppose such a sail, of area 6.00 × 104 m2 and mass 6 000 kg, is placed in orbit facing the Sun. (a) What force is exerted on the sail? (b) What is the sail’s acceleration? (c) How long does it take this sail to reach the Moon, 3.84 × 108 m away? Ignore all gravitational effects and assume a solar intensity of 1 340 W/m2. Hint: The radiation pressure by a reflected wave is given by 2 (average power per unit area)/C.

Newton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it can be written as GMm F According to this law, when mass of both objects is doubled, the force r m becomes two times larger compared to original O becomes four times larger compared to original becomes quarter of the original O becomes half compared to original

In this problem we are going to compare the strength of the gravitational interaction between the Moon and the Earth and the Sun and the Earth. We will do this by finding the gravitational field g due to the Moon or the Sun, which is the acceleration that the Earth would have if it were interacting with each of them. For reference, the Moon has a mass of 7.34 × 1022 kilograms and is located 3.84 × 105 kilometers away from the Earth. The Sun, meanwhile, has a mass of 1.99 × 1030 kilograms and is located 1.49 × 108 kilometers away from the Earth.
