A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 3 m/s. But 2.5 seconds later, at the bottom of the slope, its speed is 25 m/s. What is its average acceleration?

Average acceleration = 8.8 m/s²

Explanation:

Given the following data;

Initial velocity = 3m/s

Final velocity = 25m/s

Time = 2.5 secs

To find the average acceleration;

Acceleration = v-u/t

Acceleration = 25 - 3/2.5

Acceleration = 22/2.5

Acceleration = 8.8 m/s²

Therefore, the average acceleration is equal to 8.8 meters per seconds square.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
