Please help me check these two questions A ball starts rolling down a cramp. is the value change in its kinetic energy zero or positive A spaceship has a rotating compartment which gives its passengers artificial gravity.Suppose this compartment is a cylinder with a radius of 10.7 m. In order for theartificial gravity to be the same strength as what is experienced on Earth's surface,what would the period of rotation of this compartment need to be, in seconds? The radial acceleration of the space stationa=tw²We canthat the acceleration of the space stationsayequal to gravity for a particular rotation of periodThus, The angular speed9.8w² = 2 w = √²417m = 0.957 rad/s2Thus, The period of rotation211T = 0.957 = 6.56 sTherefore the period of rotation is6.56 S15

Astronomical observatrions of our Milky Way galaxy indicate that it has a mass of about 8.01011 solar masses. A star orbiting on the galaxy’s periphery is about 6.0104 light-years from its center. (a) What should the orbital period of that star be? (b) If its period is 6.0107 years instead, what is the mass of the galaxy? Such calculations are used to imply the existence of other matter, such as a very massive black hole at the center of the Milky Way.

An astronaut circling the earth at an altitude of 400 km is horrified to discover that a cloud of space debris is moving in the exact same orbit as his spacecraft, but in the opposite direction. The astronaut detects the debris when it is 41 km away. How much time does he have to fire his rockets and change orbits? In the solution manual it says to use the gravity formula, but why ? What hints at the fact that we must employ this formula? Thank you :)
