Question

15 points!! pleas help! A rollercoaster cart that has a mass of 4500 kg has 67.5 kJ (kilojoules), or 67,500 J (joules), of gravitational potential

energy. What is its height above the ground?

PT.2

The same 4500 kg rollercoaster cart is moving with 63.0 kJ (kilojoules), or 63,000 J (joules), of kinetic energy at the

bottom of its biggest hill. What is its velocity?

Answer 1

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

I not completely sure but I hope this helped you
