4. The acceleration due to gravity on one of Saturn's moons Titan (the best moon), is 1.40 m/s2, what is the range of a projectile with a mass of 0.865 kg launched at 1.65 km/s at an angle of 45° (neglect air resistance)? What fraction of the circumference of Titan is this range?
Phobos is one of two small moons that orbit Mars. Phobos is a very small moon and has correspondingly small gravity-- it varies but a typical value is about 6mm/s^2. Phobos isn't quite round, but it has an average radius of about 11 km. What would be the orbital speed around Phobos, assuming it was round with gravity and radius as noted?
The mass of the Moon is 7.4x1022 kg, and its diameter is 3474 km. During the Apollo landings, once reaching the Moon two astronauts would get into the Lunar Module from the Command Module. The LM would then separate from the CM and descend to the surface. What is the speed of the LM, in a circular orbit around the Moon at an altitude of 277km What is the period of that orbit?
Phobos is the closer of Mars' two small moons, has a circular with radius 9400 km from the center of Mars, a planet of mass 6.4 x 10 kg^23 How long does it take Phobos to complete one orbit of Mars Express your answer in hours.
The mass of the moon is 7.34 × 1022 kg, and its radius is about 1.74 × 106 m (a) What is the value of “gmoon”, that is, the acceleration of gravity for a falling object near the surface of the moon? (b) What is the escape speed (from the moon) for an object on the surface of the moon? (c) What is the escape speed from the earth for an object that is as far from the earth as...
1) Two blocks (A and B) are in contact on a horizontal friction-less surface. A 52 N constant force is applied to A horizontally pointing to the right. Given mA=4.0 kg, and mB = 40kg, what is the magnitude of the force of A and B? 2)The acceleration due to gravity on one of Saturn's moons Titan ( the best moon), the acceleration due to gravity is 1.40 m/s^2, what is the range of a projectile with a mass of...
Consider a spherical asteroid with a radius of 20 km and a mass of 9.25 ✕ 1015 kg. Assume the asteroid is roughly spherical. (a) What is the acceleration due to gravity on the surface of this asteroid? m/s2 (b) Suppose the asteroid spins about an axis through its center, like the Earth, with a rotational period T. What is the smallest value T can have before loose rocks on the asteroid's equator begin to fly off the surface? h
Jupiter has a mass of 1.9 x1027 kg and a radius of 69940 km. Calculate the acceleration due to gravity on the surface of Jupiter, in meters per square second. What will be the force between Jason and the Jupiter if Jason's mass is 69 kg?
Planet-X has a mass of 3.62×1024 kg and a radius of 8400 km. What is the First Cosmic Speed i.e. the speed of a satellite on a low lying circular orbit around this planet? (Planet-X doesn't have any atmosphere.) What is the Second Cosmic Speed i.e. the minimum speed required for a satellite in order to break free permanently from the planet? If the period of rotation of the planet is 19.9 hours, then what is the radius of the...
For the purposes of this problem, use the following data: mass of Comet 67P is 1 times 10^13 kg; radius of Comet 67P is 2.30 km; mass of Philae = 100 kg; mass of Rosetta = 1000 kg; radius of Rosetta's orbit was 22.3 km (a) What is the acceleration due to gravity on the surface of the comet, where Philae is? m/s^2 (b) What is the escape speed at the surface of the comet? This is the speed above...
