A water park rider (mass = 42.0 kg) starts from rest at the top of a 54.0-m tall water slide (A). The height at B is 24.0 m. Assuming mechanical energy conservation, determine the potential energy (PE) and kinetic energy (KE) values at locations A, B, and C.

scientific laws are the result of testing theories and proving them to be facts.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
