question; the work one by friction force to stop a car of mass 1000 kg moves with velocity 72km/h is
a) 72 x 10³ J
b) 2 x 10⁴ J
c) 2 x 10⁵ J
d) 4 x 10⁵ J
an explanation for future reference would be appreciated^^
Work = different of kinetic energy
W= ½ mv ²
W= ½ ×1000×20×20= 400000J
also written as 4×10^5 J
here are some information of the future of geothermal energy:
-the future of geothermal energy can pretty much be summed up with a single word: more
-scientists plan in going deeper than 120 meters
-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy
hope this !
