Appendix A physics 1 kinematics

[Evelyn]

I need help solving question 7 in the APlus Physics 1 essentials book in appendix A on kinematics. There isn't much of an explanation for the answer. Thanks!

There are several explanations I think.  I would probably use the kinematic equations (v0, v, delta_x, a, t), and use those to solve the problem.  If you're getting stuck, can you post what you've done so far, and that will give me better information to assist you?

Using the kinematic equations I had 1 = 0*1.52 + .5*a*1.52². Solving for a I got 0.865 m/s/s but the book says the answer is .855 m/s/s.

Which is certainly closely enough given various rounding / sig figs.  You got it right.
