Jason has 13720 J of gravitational potential energy standing at the top of a cliff over the lake. If he jumps off the cliff and falls to the water below, how much kinetic energy will he have when he reach the surface of the water?

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
