Homework Help: Real car going around a loop?

  1. Mar 28, 2008 #1
    We did an experiment with hot wheels and we calculated its initial velocity, maximum centripetal acceleration, and maximum g force. The length of it was 5.0cm, initial velocity was 2.1 x 10^2m/s and max. centripetal acc. was 4.0 x 10^3 cm/s^2 and max. g-force of 4.5g

    We scaled up the values to that of the real car; length of 4.9m

    This is a lab about forces and energy. What are some comments I can make about the scaled up values? I know that it would be impossible because it needs to have a max. cent. acc. of 4.0 x 10^3m/s^2 and max g-force of 4.1 x 10^3g but what are some physics behind it that makes this impossible? and how is g-force relevant for the scaled up values?? doesn't it just mean that u'll feel heavier?
