Question
A body starts from the rest and is in a uniformly accelerated motion. The coordinates of the endpoint of its graph are (x, y). Which of the following is the correct formula for the displacement of the body?
- y/x
- x/y
- ½xy
- ½(y/x)
Hint:
½xy
The correct answer is: ½xy
In the given graph the body starts from rest and is in a uniformly accelerated motion hence the slope will originate from the origin and has a straight line and the area under the slope will be of triangular shape.
Area of triangle =
Are of triangle = 1/2 xy
