2. A car of mass 1.1 x 10kg negotiates a level curve at a constant speed of 22 m/s. The
curve has a radius of 85 m.
(a) Draw an FBD of the car and name the force
that provides the centripetal acceleration.
(b) Determine the magnitude of the force named
in part (a) that must be exerted to keep the car
from skidding sideways.
(c) Determine the minimum coefficient of static
friction needed to keep the car on the road.
