A computational model predicts the maximum speed that a roller coaster car can experience, given its mass and initial height and speed. What is the maximum speed when the conditions are mass = 450 kg, initial height = 30 m, and the roller coaster car is initially at rest? a) 24.2 m/s
b) 93.9 m/s
c) 132,300 m/s
d) 30 m/s
