c) 68.22m/s
Explanation:
The centripetal force must be equal to the horizontal component (x component) of the gravitational force over the plum bob. Thus, we have
( 1 )
where M is the mass of the car, v its speed, r the radius of the curvature and g the gravity constant.
a) By replacing we obtain:
( 2 )
where it is only necessary to put the mass of the car M in (2).
b) By canceling M in (2) and taking apart r we get:

c) If the angle is 7° the speed is given by:
