Acar starts from rest and accelerates at a constant rate in a straight line. in the first second the car covers a distance of 2.0 meters. how fast will the car be moving at the end of the second second?

The solution would be like this for this specific problem:

Given:

Distance = 2.0 meters

Find:

Vx = ?

Δx =

a = 2 Δx 

Therefore, the car will be moving 8 m/s at the end of the second second.

To add, the physical vector quantity that both requires magnitude and direction is called velocity. It is also equivalent to a direction of motion and specification of its speed.

the correct choice is a .

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.
