A bowling ball of radius 4.25 in and weight of 14 lb is released from rest on a rough surface that is inclined at an angle of 40 degrees with respect to the horizontal. The static coefficient of friction is 0.2 and the kinetic coefficient of friction is 0.15. The length of the incline is 10 ft. The mass center is G, which is also its geometric center. Based on a kinetics analysis, the friction force is determined to be 2.45 N. What type of motion is this

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
