What is the speed of the glider when it returns to x=0?
<answer> 30 seconds later it turns at a rate of 70 rpm. <context> A glider with mass m = 0.250kg sits on a frictionless horizontal air track, connected to a spring with force constant k = 4.60 N/m.You pull on the glider, stretching the spring 0.100 m, and then release it with no initial velocity. The glider begins to move back toward its equilibrium position (x=0). motor provides a constant angular acceleration so that 30 secondslater it turns at a rate of 70 rpm, what is the angular accelerati. Detemine the distance d between the edge of the pane. A laser is mounted in air, m above the edge of a large, horizontalpane of crown glass (n = 1.520), as shown in the drawing.
