Aglider 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).a) what is the speed of the glider when it returns to ? b) what must the initial displacement of the glider be if its maximum speed in the subsequent motion is to be 2.60 ?

Orange juice has a lower or higher viscosity than chocolate syrup

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
