Kenny gets sent to a distant planet of radius 6.0 x 10^5m, and he tries to find out how big the planet is by kicking a sphere of 0.4 kg. He kicks it (with respect to the ground) at an angle of 45o, with a speed of 30 m/s. If the sphere lands 6 seconds later, what is the mass of that planet? Remember, the gravitational acceleration for this planet isn't the same as Earth's!

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Kenny gets sent to a distant planet of radius 6.0 x 10^5m, and he tries to find out how big the planet is by kicking a sphere of 0.4 kg. He kicks it (with respect to the ground) at an angle of 45^o, with a speed of 30 m/s. If the sphere lands 6 seconds later, what is the mass of that planet?

Remember, the gravitational acceleration for this planet isn't the same as Earth's!

For many years, astronomer Percival Lowell searched for a Planet X that might explain some of the perturbations observed in the orbit of Uranus. These perturbations were later explained when the masses of the outer planets and planetoids, particularly Neptune, became better measured (Voyager 2). At the time, however, Lowell had proposed the existence of a Planet X that orbited the Sun with a mean distance of 43 AU. With what period would this Planet X orbit the Sun?
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.
What is the escape speed from a planet of mass M = 3.1 x 1023 kg and radius R = 2.6 x 106 m? Write the answer in terms of km/s.
An object is dropped from an altitude of one Earth radius above Earth's surface. If M is the mass of Earth and R is its radius, the speed of the object just before it hits Earth is given by: GM R 0 GM 2R O GM V2R 0 GM VR 2GM R
This is a proportional reasoning calculation. You will want to set up equations, but mostly to look at how the orbital distance affects the orbital velocity, or to set up a ratio. (Once you know how it changes you'll have to multiply by the value at the surface to get an answer in m/s.) At the surface of the exoplanet HD179079 b, the orbital velocity would be 1.72E+4 m/s. What would the orbital velocity be 8 radii above the surface? m/s. Note: If your answer requires scientific notation, remember that OWL uses "e" notation: 1.1 x 105 is 1.1e5 to OWL.
Aliens declare war on Earth by dropping an asteroid on our planet. The asteroid starts at rest from a distance of 37 x 106 m from the center of Earth. Calculate the speed with which the asteroid hits Earth's surface, in km/s. Use that G = 6.7 x 10-11 N m2 / kg2, MEarth = 6 x 1024 kg, and REarth = 6 x 106 m. (Please answer to the fourth decimal place - i.e 14.3225)
Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 3.1x10^4 m/s when at a distance of 2.7x10^11 m from the center of the sun, what is its speed when at a distance of 4.7x10^10 m? Mass of the Sun is 1.99×10^30 kg. Gravitational constant is G=6.67×10^(−11) m^3 /(kg⋅s). What is the formula? (Answer: 75006.70209088 m/s)

A third particle C, of mass 90.0 ma, is to be placed on the x axis and near particles A and B. In terms of distance d, at what x coordinate should C be placed so that the net gravitational force on particle A from particles B and C is zero? B.
