Alandfill in minnesota receives an average of 50 cm of rainfall per year. sixty percent of the water runs off the landfill. the landfill has a surface area of 5000 m2. the leachate from the landfill is treated for cadmium and other toxic metals. the present leachate collection system is 80% efficient.
what is the volume (in m3) of leachate that is treated per year?
the answer is d my friend
the child has kinetic energy (ke) because she's moving, and gravitational potential energy (gpe) because she's off the ground.
ke = 1/2mv²
ke = 1/2 (20 kg)(5 m/s)²
ke = 50 j
ug (gravitational potential energy) = mgy
ug = (20)(9.8)(2) = 392 j
