#17. a filled treasure chest of mass 375 kg with a long rope tied around its center lies in the middle of a room. dirk wishes to drag the chest, but there is a coefficient of static friction of = 0.52. if the angle between the rope and the floor is 30o, what is the magnitude of the tension required to just get the chest moving?

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. 

The correct answer should be b let me know if i’m wrong

Simple, don't do it. just don't go to that dock
