Evelyn Posted October 9, 2017 Share Posted October 9, 2017 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! Quote Link to comment Share on other sites More sharing options...
0 FizziksGuy Posted October 9, 2017 Share Posted October 9, 2017 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? Quote Link to comment Share on other sites More sharing options...
0 Evelyn Posted October 9, 2017 Author Share Posted October 9, 2017 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. Quote Link to comment Share on other sites More sharing options...
0 FizziksGuy Posted October 10, 2017 Share Posted October 10, 2017 Which is certainly closely enough given various rounding / sig figs. You got it right. Quote Link to comment Share on other sites More sharing options...
