A roller coaster car descends a track from point A to point B.
The gravitational potential energy of the roller coaster car decreases by 222950 J.
The mass of the roller coaster car is 650 kg.
Calculate the vertical height, hhh, of the descent.
Use g=9.8 N/kgg = 9.8 \text{ N/kg}g=9.8 N/kg.
Use the equation:
change in gravitational potential energy=mass×gravitational field strength×change in height \text{change in gravitational potential energy} = \text{mass} \times \text{gravitational field strength} \times \text{change in height} change in gravitational potential energy=mass×gravitational field strength×change in height
