The graph represents the position of a particle along the x axis as a function of time.  Which interval has the highest magnitude of acceleration?
A) a-b 
B) b-c 
C) c-d 
D) d-e 
E) They have equal acceleration

Quizplus · Accepted Answer

The magnitude of acceleration is highest when the slope of the graph is steepest. This occurs in interval b-c where the particle is accelerating rapidly in the positive x-direction.
