The nardo ring is a circular test track for cars. it has a circumference of 12.5 km. cars travel around the track at a constant speed of 100 km/h. a car starts at the easternmost point of the ring and drives for 7.5 minutes at this speed. what is the magnitude of the car's displacement, in km, from its initial position?

The magnitude of the car's displacement is 0 m

Acceleration is rate of change of velocity.

a = acceleration (m / s²)v = final velocity (m / s)

u = initial velocity (m / s)

t = time taken (s)

d = distance (m)

Let us now tackle the problem!

Given:

Circumference = C = 12.5 km

Speed = v = 100 km/h

Time = t = 7.5 minutes = 0.125 h

Unknown:

Displacement = d = ?

Solution:

Firstly, we will calculate the distance traveled by the car.

Since the circumference of the track is equal to the distance traveled by the car, the car returns to its starting point.

This means that the displacement made by the car is 0 m.
