An automobile (and its occupants) of total mass m = 2000 kg, is moving through a
curved dip in the road of radius r = 20 m at a constant speed v = 20 m/s. for this analysis, you can
neglect air resistance. consider the automobile (and its occupants) as the system of interest. use g =
10 m/s2.

calculate the normal force exerted by the road on the system (car and its occupants).
a) 60,000 n
b) 20,000 n
c) 40,000 n
d) 50,000 n
e) 30,000 n

Normal force, N = 60000 N                      

Explanation:

It is given that,

Mass of the automobile, m = 2000 kg

Radius of the curved road, r = 20 m

Speed of the automobile, v = 20 m/s

Let N is the normal and F is the net force acting on the automobile or the centripetal force. It is given by :

N = 60000 N  

So, the normal force exerted by the road on the system is 60000 Newton. Hence, this is the required solution.

true tan speed = ang vel x radius
