For chapter 1, on page 20, when they said they arrived at the equation y= 1/2at by using equation v= vo+at, isn't this wrong? shouldn't it be from equation y= vot + 1/2 at^2?
on page 23, they also said, using equation 1.18 which is y=1/2at^2 ? when it should be v=vo +at, right? and the answer should be -4s not 4s, right?
I think there is an error they made or am I wrong?
