Homework Statement
A truck accelerates uniformly from rest to 48km/h in 20s, holds speed for 2 minutes, and then accelerates to 100km/h at a rate of 17m/s^2. How long does it take, from rest, to reach 100km/h and what distance it traveled in this time?
The book says it takes 148.5s, and I keep getting 140.85s.
For distance the book says 1904m, and I been getting lower at 950.57m.
I was hoping someone could just check the answers for me, since I am doing a course from a book that has had a lot of mistakes thus far, if it turns out that my answers are wrong I will post my what I've been doing to get some help on it. Thanks much!
