Answer:
The smallest radius will be four (4) times the initial radius
Explanation:
The car maintains a constant angular speed. According to Newton's Second Law F = m a
1.
2.
Replacing 2 in 1
3.
Where:
Fr= Frictional force
Rp= Initial Radius
An= Centripetal Acceleration
M= Mass
V= Velocity
Also we have that:
4.
μ= Coefficient of friction between the car and the surface
M= Mass
W= Weight
G= Gravity
r is cleared from equation 3
5.
Replacing 4 in 5
6.
Simplifying
7.
Now we have a new velocity equal to twice the initial velocity, We replace it by 2v in equation 7
8.
Computing
9.
Replacing 5 in 9
