The velocity of the car is
.
Explicação
## Step 1The 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. ## Step 2To find the velocity, we divide the displacement by the time. This gives us the formula:###
where
is the velocity,
is the displacement, and
is the time.## Step 3Substituting the given values into the formula, we get:###
## Step 4The direction of the velocity is west, as the car moves west. Therefore, the velocity of the car is 100m/s west.
