Acrane raises a 150 n weight to a height of 2.0 m in in 5.0 s. the crane does work at a rate of

The work done is (force) x (distance) = (150N) x (2m) = 300 joules.

The crane does the work at the rate of (300 J) / (5 sec) = 60 joules per second.

That rate ... (work done) / (time to do the work) ... is called power.

That 60 joules per second is called 60 watts .

Hahahah jsu’s hsjshshsh. shjshshshsh.

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.
