A massive roller coaster is moving at 22m high and weighs 96kg. At the top of the hill. Calculate its potential energy

i got 10.28 but that rounds up to 10.3

7/2

(decimal: 3.5)

welcome ; )

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
