Acurve in a road forms part of a horizontal circle. as a car goes around it at constant speed 14.0 m/s, the total force exerted on the driver has magnitude 110 n. what are the magnitude and direction of the total vector force exerted on the driver if the speed is 24.0 m/s instead?

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.
