The cake company truck is on it's way deliver a cake for a party when it rounds a curve of radius 20 m at a speed of 12 m/s. What coefficient of friction is needed between the cake pan and the truck in order to keep the pan from slipping?
please show work!
To avoid slipping, the maximum static friction force,
M g Us,
must exceed the centripetal force
Set them equal and solve for the static friction coefficient, Us.
Us = V^2/(R*g)
That will be the minimum value required.
