Acar moves 30 mi/h to the north. every second, the velocity increases by 3 mi/h. which option represents the acceleration as a vector quantity?

30 mi/h north

30 mi/h

3 mi/h/s

3 mi/h/s north

Explanation:

It is given that, a car moves 30 mi/h to the north. Every second, the velocity increases by 3 mi/h. We know that the rate of change of velocity is called the acceleration of an object.

Here, the velocity increases at the rate of 3 mi/h. It shows the rate of change of velocity i.e. acceleration.

Since,

a = 3 mi/h/s

The direction of acceleration is as same as velocity i.e. in north direction. So, the correct option is (d) " 3 mi/h/s north ".

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
