The magnitude of the horizontal component of the normal force required is 18225 N.
To calculate the magnitude of the horizontal component of the normal force required to produce the centripetal acceleration in the absence of any friction, we can use the following formula:
Horizontal component of the normal force (N_horizontal) = (m * v^2) / r
where:
m = mass of the car (1000 kg)
v = speed of the car (27 m/s)
r = radius of curvature (40 m)
Now, plug the values into the formula:
N_horizontal = (1000 kg * (27 m/s)^2) / 40 m
N_horizontal = (1000 kg * 729 m^2/s^2) / 40 m
N_horizontal = 729000 kg m^2/s^2 / 40 m
Now, let's convert kg m^2/s^2 to Newtons (N):
1 N = 1 kg m/s^2
N_horizontal = 729000 N / 40
N_horizontal = 18225 N
So, the magnitude of the horizontal component of the normal force required is 18225 N.
