Question

A roller coaster cart of mass m = 201 kg starts stationary at point A, where h1 = 27.7 m and a while later is at B, where h2 = 7.1 m.
The acceleration of gravity is 9.8 m/s
2.
What is the potential energy of the cart
relative to the ground at A?
Answer in units of J.
(201*27.7*9.8)-(201*7.1*9.8)=40577.88J What did I do wrong

They are asking for the PE at A only:

PE = m*g*h1
