Answer:
97200 J
Explanation:
Applying,
K.E = mv²/2.................. Equation 1
Where K.E = Kinetic Energy, m = mass of the roller coaster car, v = velociety of the roller coaster car.
From the question,
Given: m = 600 kg, v = 18 m/s
Substitute these values into equation 1
K.E = (600×18²)/2
K.E = 97200 J.
Hence the kinetic energy of the car is 97200 J
