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?
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...
