As there are actually not any losses (e.g., friction), her taking off PE = mgH = a million/2 mV^2 = KE on the backside. So V = sqrt(2gH) = sqrt(2*9.8*one hundred twenty 5) = 40 9.49747468 = 40 9.5 mps. ANS. The lesson precise that's that that's particularly common as quickly as you be attentive to the physics, it fairly is the conservation of ability.... Show More
