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

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
