a 550 kg roller coaster car is on a hill 91 meters above the ground. how much gravitational potential energy does the roller coaster car have? remember : eg = mgh g = 10 m/s² eg = ?j
Answer
# Explanation:
## Step1: Identify given values
$m = 550$ kg, $g=10$ m/s², $h = 91$ m
## Step2: Substitute values into formula
$E_g=mgh=550\times10\times91$
## Step3: Calculate result
$E_g = 550\times910=500500$ J
# Answer:
500500 J
