. Tiffany, who is opening in a new Broadway show, has some limo trouble in the city. With only 8 minutes until curtain time, she hops in an Uber and they speed off to the theater down a 1000 meter long one way street at a speed of 25 m/s. At the end of the street, the Uber driver waits at a traffic light for 1.5 minutes and then continues onto a 1700 meter long traffic filled avenue on which he is able to travel at a speed of only 10 m/s. Finally, this brings them to the theater. a. Does Tiffany arrive before the theater lights dim?

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?
