A car initially traveling at 30 m/s passes a road sign located 750 meters ahead in a time of 12 seconds. When the car reaches the road sign, the driver applies the breaks and brings the car to rest at a traffic light located 900 meters ahead of the road sign. Determine the cars velocity when it reaches the road sign in m/s
To determine the car's velocity when it reaches the road sign, we can use the formula:
velocity = distance / time
Given that the car travels a distance of 750 meters in a time of 12 seconds, we can calculate its velocity.
velocity = 750 meters / 12 seconds
≈ 62.5 m/s
Therefore, the car's velocity when it reaches the road sign is approximately 62.5 m/s.
