Your 64-cm-diameter car tire is rotating at 3.4 rev/s when suddenly you press down hard on the accelerator. After traveling 260 m, the tire's rotation has increased to 5.5 rev/s. What is the tires angular acceleration?

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

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.
