Answer:
Image result for position (m) 80 60 40 20 - 20 -40 10 20 30 40 50 time (sec) What is the displacement from 15 to 40 sec? a 20 m b Оооо - 20 m -100 m с 100 m
The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
