A speed camera takes two photographs of a car.
Photo 2 was taken 0.5 seconds after Photo 1.
Marks on the road are 0.8 meters apart.
Calculate the average speed of the car in m/s.
I tried 1.6 but it does not work
It's 7.2 m/s buh gives 2 marks
I apologise sincerley
To calculate the average speed of the car, we need to use the formula:
Average Speed = Distance / Time
First, let's determine the distance traveled by the car. Since the marks on the road are 0.8 meters apart, the distance between Photo 1 and Photo 2 is 0.8 meters.
Next, we need to find the time it took for the car to travel this distance. Given that Photo 2 was taken 0.5 seconds after Photo 1, we know that the time elapsed is 0.5 seconds.
Using these values, we can now calculate the average speed:
Average Speed = Distance / Time
Average Speed = 0.8 meters / 0.5 seconds
Dividing 0.8 meters by 0.5 seconds gives us an average speed of 1.6 meters per second (m/s).
Therefore, the average speed of the car is 1.6 m/s.
