Ahockey puck is set in motion across a frozen pond. if ice friction and air resistance are neglected, the forced required to keep the puck sliding at constant velocity isa. equal to the weight of the puckb. the weight of the puck divided by the mass of the puckc. the mass of the puck multiplied by 9.8 m/sd. zero newtons

Ais the answer hope this

What formula  this one  (x_/

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.
