The position of a particle moving along a coordinate line is s equals StartRoot 76 plus 6 t EndRoot, with s in meters and t in seconds. Find the rate of change of the particle's position at t equals 4 sec. The rate of change of the particle's position at t equals 4 sec is 104 4 m divided by sec.

Which accurately compares concave and convex lenses?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
