A car is driving north of the highway. The driver speeds up to 180 m/s. It took 8 seconds for the car to speed up. What is the acceleration?

What was the initial speed the car was driving at?

I’m not sure about this question

Ican’t exactly answer this, but i can try to give a bit more info here.
astronomers are able to calculate a star’s life expectancy depending on its mass. (a larger star burns more gas, therefore having a shorter life span).
so astronomers can definitely predict the death of stars and the times they will die.
i hope this was in some way : )
