Suppose our experimenter repeats his experiment on a planet more massive than Earth, where the acceleration due to gravity is g=30 m/s2. When he releases the ball from chin height without giving it a push, how will the ball's behavior differ from its behavior on Earth? Ignore friction and air resistance. (Select all that apply.)

	It will take more time to return to the point from which it was released.
	It will smash his face.
	Its mass will be greater.
	It will take less time to return to the point from which it was released.
	It will stop well short of his face.

Planet Lex is four times as massive as the Earth and has a radius four times...

Planet Lex is four times as massive as the Earth and has a radius four times larger than the Earth's radius. Note: You do not have to express your answers in scientific notation. Mass of the Earth = 5.97 x 1024 kg Radius of the Earth = 6.37 x 106 m a. What is the value of the acceleration due to gravity (in m/s2) on the surface of this planet? Round off your answer up to two decimal digits. b....

Is the acceleration of Mars' acceleration much greater than that of the Earth (encircling their orbit around the sun)? Justify your answer. The mass of Pluto was unknown until it was discovered that it had a moon. Explain how to estimate the mass of Pluto. Explain how this made it possible to estimate the mass of Pluto.

A planet has the same density as Earth but has a surface gravitational acceleration of nine times that of the Earth (a person would instantly black out if placed on the surface). What is the escape velocity from the planet? If the planet was in an orbit of 1 AU from a 1 M⊙ star, what is the maximum distance that a moon could orbit the planet?

More than 6.7 billion people inhabit our planet. Due to advances in technology and invention of agriculture, we have skirted the environmental resistance to growth. We have also impinged upon other species demographics. First describe the human population growth. (Is logistic? If so, what phase of the logistic growth curve? What type of survivorship curve? Are we r-selected or k-selected?) Next, describe what you feel would be a fair way to control our population growth?

A projectile is launched on a planet other than Earth at a velocity of 38.1 m/s 30.0o above the horizontal. The ground slopes down in the direction of travel, so the projectile impacts the ground 37.9 m below the level from which it was launched. If the horizontal distance it travels is 419 m, what is the magnitude of the acceleration of gravity near the surface of the alien planet?

A projectile is launched on a planet other than Earth at a velocity of 44.8 m/s 30.0o above the horizontal. The ground slopes down in the direction of travel, so the projectile impacts the ground 47.3 m below the level from which it was launched. If the horizontal distance it travels is 376 m, what is the magnitude of the acceleration of gravity near the surface of the alien planet?

You are once again on the Pizza Planet of Alpha Centauri IV where the acceleration due to gravity is still gP = 9.12 m/s2 . Luigi is on one of the long, straight, moving walkways which has a constant velocity of 12.5 m/s, but he is late for an important engagement with Mario so is walking at a constant velocity of 5.50 m/s with respect to the moving walkway. You observe Luigi from an adjacent walkway that is moving at...

1. On a planet where the gravitational acceleration is g=10 m/s², a solid cube of wood measuring one foot on each edge exerts a uniform pressure of 3048 Pa on a flat tabletop due to its weight. Find the wood's specific gravity and state whether it will float on water. One foot is 0.3048 m. 2. A crown is made of an alloy consisting of gold (19 g/cc) and copper (9 g/cc). It weights 35 N in air, and 32.5...

Classical Mechanics problem: Suppose you are on a perfectly spherical planet and measure the free-fall acceleration to be g = g0 at the North Pole. (This planet is not necessarily Earth!) At the equator, you measure g = λg0 (with 0 ≤ λ ≤ 1). Find g(θ), the free-fall acceleration at colatitude θ as a function of θ.
