Atennis player is hitting a 58 gram tennis ball back across the net. when the racquet and the ball first make contact, the ball is moving at 30 m/s 15⁰ below the positive x-axis. when the ball leaves the racquet, it is moving at 40 m/s 15⁰ above the negative x-axis. if the ball is in contact with the racquet for 0.08 s, what is the average net force acting on the tennis ball while it is in contact with the racquet? air resistance and the force of gravity are negligible when compared to the force by the tennis racquet.

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
