- a) Which is going faster?
- b) Which will reach the target point early?
- c) How many times objects will meet?
Answer. Posted on Thursday, March 5, 2015.
a) The slope of the position-time graph gives the velocity. The faster the object goes, the greater the slope of the position-time graph. Thereby, the object B is going faster.
b) Both objects will reach their targets at the same time. The object A will be at the point K when the object B will be at the point L.
c) The intersection point on a position-time graph means that the two objects have the same position at that time. Thereby, the objects will never meet each other, because there are no intersections of the graphs.
