(a) How quickly would you have to throw the ball so that the ball enters a perfectly circular orbit around Earth? (Assume your height is much less than Earth's radius). (b) How long would the ball take to complete one orbit? (c) Let's say you throw the ball with 1.2× the speed found in (a). What is the semi-major axis of the new elliptical orbit of the ball?

Part A Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 2.1×104 m/s when at a distance of 2.6x1011 m from the center of the sun, what is its speed when at a distance of 4.0x1010 m. Express your answer in meters per second. νη ΑΣφ ? m/s
Europa orbits Jupiter at a distance of 6.7 x 108 m from Jupiter's cloudtops (the surface of the planet). If Jupiter's mass is 1.9 x 1027 kg and radius is 6.8 x 107 m, what is the speed of Europa as it orbits in m/s? Round to the nearest hundredth. Don't worry about putting units, just put the number.
A 2.0 kg rock is thrown horizontally from the top of a 100-meter-high cliff on Planet Unicorn with a speedof 15 m/s. The mass of Planet Unicorn is 1x1025 kg and the top of the cliff is approximately 4000 kmfrom the center of the planet.a) What is the value of the acceleration due to gravity on Unicorn in m/s2 ? b) How far from the base of the cliff does the rock land? A force of 40.0 N is required to pull the same rock at a constant velocity across a smooth glasssurface on Earth. What force would be required to perform the same experiment on PlanetUnicorn?
Deimos, a moon of Mars, is about 12 km in diameter with mass 2.0 × 10¹5 kg. Suppose you are stranded alone on Deimos and want to play a one-person game of baseball. You would be the pitcher, and you would be the batter! a. With what speed would you have to throw a baseball so that it would go into a circular orbit just above the surface and return to you so you could hit it? Do you think you could actually throw it at this speed? b. How long (in hours) after throwing the ball should you be ready to hit it? Would this be an action-packed baseball game?
QUESTION 12 A meteoroid is traveling straight toward the moon at 2,000 m/s when it is at an altitude of 2,500 km above the moon. What is the speed of the meteoroid just when it strikes the surface of the moon? The radius of the moon is 1.737 x 106 m, and the mass of the moon is 7.348 x 1022 kg. O a. 4,150 m/s O b. 2,710 m/s O c. 1,130 m/s d. 1780 m/s O e. 3,200 m/s
QUESTION 17 In a distant solar system, a planet of mass 5.0 x 1024 kg orbits a sun of mass 3.0 x 1030 kg at a constant distance of 2.0 x101 m. How many earth days does it take for the planet ot execute one complete orbit about the sun? a. 660 days b. 460 days с. 360 days d. 260 days е. 560 days
A number of gas giant planets orbiting other stars at distances less than 1 A.U. have been discovered. Because of their proximity to their parent stars, and their compositional similarity to Jupiter, they have been labeled “Hot Jupiters”. The orbital radius of one of these planets is 0.06 A.U. with average orbital speed 600 km/sec. What is the length of this planet’s year in Earth (solar) days? Estimate the mass, M, of its parent star in terms of the mass of the sun (M) using Newton’s first form of Kepler’s 3rd Law. Calculate the star’s luminosity, L, in terms of the luminosity of the sun (L☉), Note: (LL=MM4where L ~ 4 × 1026 W ). The radius of this planet is 1.5 times the radius of Jupiter. Assuming its equilibrium temperature is the temperature at which the planet radiates as much energy as it receives from its star, estimate the temperature of the planet. The value of the planet’s albedo is 0.8. (NOTE: The intensity of the star’s radiant power at a distance d from the star is…
Two satellitess, and S, orbit around a planet P in circular orbits of radil r, = 5.15 x 106 m, and r, = 8.40 x 106 m respectively. If the speed of the first satellite S, is 1.65 x 10 m/s, what is the speed of the second satellite S,? m/s
You are on a space station, in a circular orbit h = 500 km above the surface of the Earth. You complete your tasks several days early and must wait for the next mission from the surface to bring you home. After days of boredom, you decide to play some golf. Walking on the space station surface with magnetic shoes, you tee up a golf ball. You hit it with all of your might, sending it off with speed υrel, relative to the space station, in a direction parallel to the velocity vector of the space station at the moment the ball is hit. You notice that you then orbit the Earth exactly n = 2.00 times and you reach up and catch the golf ball as it returns to the space station. With what speed υrel was the golf ball hit?
How many years does it take for planet to go around the sun if its distance is 2.1 times away from the sun as the earth is. A 80 kg person, from the top of a 13 m cliff, throws a 100 g ball at an angle of 30 degrees above the horizontal. With what speed will the ball hit the ground below? (g = 9.8 m/s2).
Assume that planet A has radius RA and mass MA, and planet B has radius Rg and mass Mg. Let ga and gg are the accelerations due to gravity at their surfaces, respectively. If MA = Mg, and RA = 2Rg The ratio (g,/Ba) is: A. 1 B. 2 C. 4 D. 0.5 E. 0.25
