Question
A body starts from the origin and is in a uniformly accelerated motion. The coordinates of a point on its graph are (x,y). Which of the following is the correct formula for the acceleration of the body?
- (x-y)/(y-x)
- (y-x)/(x-y)
- x/y
- y/x
Hint:
y/x
The correct answer is: y/x
The acceleration of the body can be calculated by the slope of the graph.
As the slope originates from the origin,
Slope = y/x = Acceleration of the body.
