**bobpursley**, Tuesday, February 22, 2011 at 2:21pmchange velocities to m/s

Then, sketch the bank and force vectors parallel to the bank.

1) mg*sinTheta=mv^2/r * cosTheta

where v=75km/hr in m/s

solve for tan theta (sin/cos).

verify that. Now, you increase speed, same angle.

mg*sinTheta+mu*mg*cosTheta=mv^2/r * cosTheta

so find mu. How is the easy way? divid e by cos theta , you know tan theta.

v= new speed (95 in m/s), solve for mu.
