The chart shows data for four moving objects. Which object has the greatest acceleration? ​​

Y

Explanation:

Acceleration = (v-u)/t

W = (29-11)/6 = 3

X = (34-10)/12 = 2

Y = (40-12)/7 = 4

Z = (28-20)/8 = 1

So the answer is Y = 4.

Hope this will help. Please mark me brainliest.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
