Question

A car was at a red light. When it turned green, the car accelerated to 25 km/hr in 5 sec. Calculate the acceleration. Was the car speeding up or slowing down?

Answer 1

Answer:

It accelerated at 5 km/hr/s or the car was going 5 km/h faster each second.

The car was speeding up

Step-by-step explanation:

To find an estimated acceleration, you just take the speed it got to and divide it by the tie it took to get there

s/t = a        <---- where s = speed   t = time   a = acceleration

We know it was speeding up because it was at a red light so it was stopped. Then when it turned green, then the car would have started moving
