The mass of Mars is 1/10 times that of Earth, the diameter of Mars is 1/2 that of Earth Quantitative Analysis A. Derive the equation for gravitational, g, due to a planet. B. Let g be the gravitational field strength on Earth's surface. Derive an expression for the gravitational field on the surface of Mars without plugging in a value for the mass or radius of Mars. Argumentation C. A rock is dropped 2.0 meters above the surface of Mars. Does this rock take a longer or a shorter time to fall than a rock dropped 2.0 m above the surface of Earth? D. On the internet, a student finds the following equation for the time an object will take to fall to the ground from a height h, depending on the mass and radius of the planet the object is on: t = underroot 2hG/MR2. Regardless of whether this equation is correct, does it agree with your qualitative reasoning in Part C? In other words, does this equation for t have the expected dependence as reasoned in Part C? E. Another student deriving an equation for the time it takes for an object to fall from heighth makes a mistake and comes up with: t = underroot R2/2GMh. Without deriving the correct equation, how can you tell that this equation is not plausible in other words, that it does not make physical sense? Briefly explain your reasoning,

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
