Apolice officer in hot pursuit drives her car through a circular turn of radius 353 m with a constant speed of 74.1 km/h. her mass is 54.1 kg. what are (a) the magnitude and (b) the angle (relative to vertical) of the net force of the officer on the car seat? (hint: consider both horizontal and vertical forces.)

Part a)

Part b)

the angle relative to vertical is 90 degree

Explanation:

When car is moving in circle with uniform speed then the force on the car is always towards the center of the circle

This force is known as centripetal force

now we have

m = 54.1 kg

Part b)

Since there is no acceleration of car in horizontal direction while it has vertical acceleration towards the center

so the angle relative to vertical is 90 degree
