A30 gram bullet is shot upward at a wooden block. the bullet is launched at the speed vi. it travels up 0.40 m to strike the wooden block. the wooden block is 20 cm wide and 10 cm high and its thickness gives it a mass of 500 g. the center of mass of the wooden block with the bullet in it travels up a distance of 0.60 m before reaching its maximum height.

Ithink the answer would be a

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.
