"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?
Answered by Chanz
a = v^2/r
µ = Ff/Fn = (v^2/r)/g
(m's cancel)
Answered by Rosie
a=6.6m/s^2?

I'm still confused with m I got a negative number which is wrong
Answered by Rosie
m=.00192?
