"Crash" Jackson approaches a rotary in his 3,500 kg Maserati. It's radius of curvature is 95meters but his speed is 25 m/s. What is his acceleration in m/sec/sec and find his coefficient of friction between his tires and the road?

Answer 1

a = v^2/r
µ = Ff/Fn = (v^2/r)/g
(m's cancel)

Answer 2

a=6.6m/s^2?

I'm still confused with m I got a negative number which is wrong

Answer 3

m=.00192?
