Between the orbits of Mars and Jupiter, several thousand small objects called asteroids move in nearly circular orbits around the Sun. Consider an asteroid that is spherically shaped with radius r and density 2100 kg/m^3.
Part A): You find yourself on the surface of this asteroid and throw a baseball at a speed of 24 m/s. If the baseball is to travel around the asteroid in a circular orbit, what is the largest radius asteroid on which you are capable of accomplishing this feat?
Part B): After you throw the baseball, you turn around and face the opposite direction and catch the baseball. How much time T elapses between your throw and your catch?
a golf ball rolls off a horizontal cliff with an initial speed of 11.4 ms. the ball falls a vertical distance of 15.5 m
Imagine four resistors: R1=600 ohms, R2=600 ohms, R3=300 ohms, R4=300 ohms. R1, R2, and R3 are connected together in a parallel plane; then R4 is connected in series with them; and finally the combination of all four resistors is connected to a 50..
