- Calculate the kinetic energy of a 4.3 x 10^3kg satellite moving at a speed of 4.8 km/s Round your answer to 2 significant digits.Why does the gravitational attraction between the Sun and Mercury vary? Would it vary if the orbit of Mercury were perfectly circular?Suppose the Sun's orbital speed were 440 km/s. What would be the mass required to keep the Sun in its orbit?
- Law of gravitation gives the gravitational force between (a) the earth and a point mass only (b) the earth and Sun only (c) any two bodies having some mass (d) two charged bodies onlyAmy is very concerned about his weight but seldom does anything about it. After learning about Newton's law of universal gravitation in Physics class, he becomes all concerned about the possible effect of a change in Earth's mass upon his weight. During a (rare) free moment at the lunch table, he speaks up "How would my weight change if the mass of the Earth increased by 10%?" How would you answer Amy?Why don't you feel a gravitational force from the text book you're reading?
- If the satellite were to increase its orbital radius, how would this affect its acceleration around Earth?4. Show that when a satellite is in elliptical orbit, its speed v is given by *² = (²- - - ) k * and when in parabola orbit v² 2k == rHow far away would an observer need to move away from the sun to observe no gravity coming from the sun?
