Arocket is launched straight upward with a velocity of 90 m/s. it slows down, reverses direction, and returns to earth. what is the rockets velocity at its highest point above the ground. a. 0.078 m/s b. 0 m/s c. -7.0 m/s d. 13 m/s e. -13 m/s

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
