To find the friction force on the car, we can use the centripetal force formula:
F = (m * v^2) / r
where
m = mass of the car = 1079.1 kg
v = velocity of the car = 15.05 m/s
r = radius of the curve = 102.1 m
First, we need to find the centripetal force acting on the car:
Fc = m * v^2 / r
= 1079.1 kg * (15.05 m/s)^2 / 102.1 m
= 1784.4 N
The centripetal force is provided by the friction force between the car's tires and the road. Therefore, the friction force can be found by:
Ff = Fc
Ff = 1784.4 N
Therefore, the size of the friction force on the car is 1784.4 N.
