近日笔者在参考陕西师范大学出版社出版的《高中物理竟赛解题指导》一书时 ,发现该书第 1 0 2页对题8的解答是不完整的 .原题及其解答如下 :图 1“一块质量为m的滑块从倾角为θ的斜面上A点滑下 ,初速度为v0 ,滑块与斜面之间的动摩擦因数为 μ(图 1 ) .已知滑块从A点到弹簧形变 Recently, when the author consulted the book “Guidance on Problem Solving of Physics Competition in Senior High School” published by Shaanxi Normal University Press, he found that the answer to Title 8 on the twentieth page of the book was incomplete. The original question and its solution are as follows: 1 "A block of mass m slides down from point A on the slope of inclination θ, the initial velocity is v0, and the dynamic friction coefficient between the slider and the slope is μ (Figure 1). Known slider from point A to Spring deformation
