Question

Under what condition(s) is the magnitude of average velocity of an object equal to its average speed? A car & a bike is moving at speed of 45 km/h and 40 m/s respectively. Determine wichl is faster?​

Answer 1

Answer:

AS WE KNOW, average velocity is the distance covered in same intervals of time in a particular direction. But average speed doesn't depend on direction.

So when there is no change of direction of the moving object, then the average speed and velocity are same.

Now.... next thing you asked is....

45 km h⁻¹ = 45X1000/60X60 m s⁻¹

                = 45000/3600 m s⁻¹

                = 12.5 m s⁻¹

So, the speed of bike is faster than car.
