The world’s fastest car can accelerate from rest to 60 mph(27m/s) in 2.2 seconds. What is the magnitude of its acceleration?

Hi there! :)

Find the acceleration by finding the change in velocity over time:

(vf - vi) / (time) = acceleration over the interval

*Remember, an object at rest has a velocity of 0 mph, and use the correct units for speed that would result in an acceleration involving meters / seconds.*

(27 - 0) / (2.2) = 27 / 2.2 ≈ 12.27 m/s²

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
