A police car waits in hiding slightly off the highway. A speeding car is spotted by the police car doing 63 m/s. At the instant the speeding car passes the police car, the police car accelerates from rest at 3 m/s2 to catch the speeding car. How long (in s) does it take the police car to catch the speeding car

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

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. 

Answer(b) both involve the use of levers;
