South of the equator, in the midst of the Brazilian rain forest, sits the bustling coastal city of Rio de Janeiro. Known for its beautiful beaches
and tropical weather, Rio de Janeiro is a city that loves to celebrate.
Every February, Rio hosts Carnival, a huge, multiday festival that
involves floats, costumes, music, and dancing. But it's not just Carnival,
in 2014, Brazil hosted the World Cup soccer tournament, and Rio's
citizens are preparing to host the 2016 Olympics as well. With so much
going on, shouldn't you get busy booking your ticket to Rio?
Which is a subjective summary of the passage?

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
