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?

- Suppose the gravitational acceleration at the surface of a certain moon A of Jupiter is 2 m/s2. Moon B has twice the mass and twice the radius of moon A. What is the gravitational acceleration at its surface? Neglect the gravitational acceleration due to Jupiter, (a) 8 m/s2 (b) 4 m/s2 (c) 2 m/s2 (d) 1 m/s2 (e) 0.5 m/s2arrow_forwardProblem 5. Carousel that’s turning A carousel has two lanes of horses: an outer lane of radius 5.36 m and an inner lane of radius 3.78 m. When a ride starts, the carousel immediately starts rotating with some initial angular speed wo, and undergoes a constant angular acceleration a until it reaches its maximum angular speed, after which it rotates constantly at this angular speed. The carousel completes its first revolution in 23.0 s, then completes its second revolution after an additional 21.0s. At its maximum speed, the carousel completes one revolution every 14.0 s. During the ride, the horses also move up and down, and their vertical motion is independent of the angular speed of the carousel. The vertical displacement of each horse follows that of simple harmonic motion, with one up-and-down cycle lasting 3.50 s, and the height difference between each horse's highest point and lowest point being 20.3 cm. All horses start at their lowest point at the beginning of the ride. (a) Find…arrow_forwardPart A Comets travel around the sun in elliptical orbits with large eccentricities.

- Jupiter is about 300 times more massive than Earth. One might quickly conclude that an object on the surface of Jupiter would weigh 300 times more than on the surface of the Earth. For instance, one might expect a person who weighs 500 N on Earth would weigh 150000 N on the surface of Jupiter. Yet this is not the case. In fact, a 500-N person on Earth weighs about 1500 N on the surface of Jupiter. Explain how this can be.arrow_forwardA: Calculate the escape velocity from the surface of a world with mass 1.00 ✕ 1024 kg and radius 2.50 ✕ 103 km. m/s B: In Robert Heinlein's The Moon Is a Harsh Mistress, the colonial inhabitants of the Moon threaten to launch rocks down onto Earth if they are not given independence (or at least representation). Assuming a gun could launch a rock of mass m at 1.10 times the lunar escape speed, calculate the speed of the rock as it enters Earth's atmosphere.

- In recent years, scientists have discovered hundreds of planets orbiting other stars. Some of these planets are in orbits that are similar to that of earth, which orbits the sun (MsunMsun = 1.99 ×× 103030 kgkg) at a distance of 1.50 ×× 101111 mm, called 1 astronomical unit (1 auau). Others have extreme orbits that are much different from anything in our solar system. The following problem relates to one of these planets that follows circular orbit around its star. WASP-32b orbits with a period of only 2.7 days a star with a mass that is 1.1 times that of the sun. How many au from the star is this planet? Assume the orbital period of earth is 365 days. Express your answer in astronomical units.arrow_forwardSome of the most spectacular objects in the universe are fairly small: neutron stars are spheres with a diameter that's about 10km (they are remnants of old stars). Their spectacular nature is indicated by the fact that they are about as massive as the sun, i.e. 2 x 1030kg. What is the gravitational acceleration on the surface of such an object? Express your result as a multiple of g.arrow_forwardAssume 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. 0.25arrow_forward

It has a mass of approximately 1×10+27[kg]. Its actual radius is not currently known, but we do know that the radius of Jupiter is 7×107[m].
