I'm lost on this problem too! A 70kg stunt driver rounds a circular corner at 96km/hr (convert to m/s). The centripetal force on the driver is 856N. Calculate the radius in meters of the path that the driver took around the circular corner.

Answer 1

f = m v^2 / r ... r = m v^2 / f

do the suggested conversion to get the right units

Answer 2

I still don't get it where do I insert what?

Answer 3

v = (96000 m/hr) / (3600 m/s) = ? m/s

r = 70 kg * v^2 / 856 N

Answer 4

Thank you! I understand it
