The velocity of the car is \(100m/sW\).
Explicação
## Step 1<br />The velocity of an object is defined as the rate of change of displacement with respect to time. In this case, the car moves 500 meters west in 5 seconds. <br /><br />## Step 2<br />To find the velocity, we divide the displacement by the time. This gives us the formula:<br />### \(v = \frac{d}{t}\)<br />where \(v\) is the velocity, \(d\) is the displacement, and \(t\) is the time.<br /><br />## Step 3<br />Substituting the given values into the formula, we get:<br />### \(v = \frac{500m}{5s} = 100m/s\)<br /><br />## Step 4<br />The direction of the velocity is west, as the car moves west. Therefore, the velocity of the car is 100m/s west.
