Two runners start a race. after 2 seconds, they both have the same velocity. if they both started at the same time, how do their average accelerations compare?

let each runner starts from rest

v₀ = initial velocity of each runner = 0 m/s

t = time of travel = 2 sec =

a = average acceleration

average acceleration is given as

a = (v - v₀)/t

inserting the values

a =  (v - 0)/t

a = v/t

since each runner gains equal amount of speed in given time interval of "t". hence the average acceleration of each runner is same.

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.

it would be c. predictability
