What is the change in potential energy with respect to the ground of a 0.55 g son of a leech (a very effective fly for steelhead originally conceived by Mr Crane) initially cast straight up 4.0 m? a. 22 J b. 9.81 J c. 0.022 J d. 0.0054 J

Arowboat passenger uses an oar to push the boat off the dock by exerting a force of 40n for 3.0s. what impulse acts on the boat.

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

Based on this activity, is kinetic energy always transformed into potential energy?
