consider the five motion diagrams shown in the figure. each of these diagrams shows the position at equal time intervals of an object undergoing one-dimensional motion from left to right.
a) which diagram corresponds to uniformly accelerating motion, directed towards the right?
b) which diagram corresponds to uniformly accelerating motion, directed towards the left?
c) which diagram corresponds to the object initially accelerating to the right and then accelerating to the left?
d) which diagram corresponds to uniform motion with no acceleration?
e) which diagram corresponds to the object initially accelerating to the left, and then to the left?
A) B) C) D) E)
Expert Answer
a) Using the 2nd law of motion: Let the time interval of the object moving in one dimension be tPosition at t = Position at 2t = Position at 3t = Distance traveled from t to 2t = Distance traveled from 2t to 3t = If the acceleration is directed toward the right C is the correct representation of itConsidering left to be positive directionIf the body is accelerating in the direction of initial velocity it will cover more distance in the same time interval than before
