Aglider of mass 0.240 kg is on a horizontal track, attached to a horizontal spring of force constant 6.00 n/m. there is friction between the track and the glider. initially the spring (whose other end is fixed) is stretched by 0.100 m and the attached glider is moving at 0.400 m/s in the direction that causes the spring to stretch farther. the glider comes momentarily to rest when the spring is stretched by 0.112 m. how much work does the force of friction do on the glider as the stretch of the spring increases from 0.100 m to 0.112 m?

b) what is the coefficient of kinetic friction between the glider and the track?

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
