A2.0-kg mass is projected from the edge of the top of a 20-m tall building with a velocity of 24 m/s at some unknown angle above the horizontal. disregard air resistance and assume the ground is level. what is the kinetic energy of the mass just before it strikes the ground?0.97 kj.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Urgent pls a. coal consumption levels off and remains flat. b. petroleum, natural gas, and renewables show an increase in consumption c. more nonrenewable resources continued to be consumed than renewable. d. there is little projected increase in nuclear energy use. e. carbon dioxide emissions are projected to decline as we approach 2040. global energy consumption is defined as the total energy used by an individual or organizations from around the world. use the graph above to analyze the projected energy consumption from now until 2040. which statements in the prompt apply? a) a, b, d b) b, c, d c) a, c, d d) a, b, c, d
