A2.37-kg rock is released from rest at a height of 22.2 m. ignore air resistance and determine (a) the kinetic energy at 22.2 m, (b) the gravitational potential energy at 22.2 m, (c) the total mechanical energy at 22.2 m, (d) the kinetic energy at 0 m, (e) the gravitational potential energy at 0 m, and (f) the total mechanical energy at 0 m.

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
