Acar moving east at 45 km/h turns and travels west at 30 km/h. what is the magnitude and direction of the change in velocity?

The magnitude and direction of the change in velocity is 75 m/s in west.

Explanation:

Given that,

Velocity of car = 45 km/h in east

Velocity of car = 30 km/h in west

We need to calculate the magnitude of the change in velocity

Using formula of change in velocity

Change in velocity = final velocity - initial velocity

Put the value into the formula

The direction of the the change in velocity is toward west.

Hence, The magnitude and direction of the change in velocity is 75 m/s in west.

Newton's First and Second Laws of Motion. A force is a push or a pull on an object. When you place a book on a table, the book pushes downward on the table and the table pushes upward on the book. The two forces are equal and there is no resulting motion of the book
