Answer:
First graph
Step-by-step explanation:
Here we need to tell which graph best represents the relationship between kinetic energy and mass . As we know that ,
KE = 1/2 mv²
Here we will plot KE on y axis and mass of x axis. And it is in form of y = mx + c .On comparing the given equation with ,
y = mx + c
Therefore the line will be straight and will pass through origin with a slope v²/2 .
From the attached graphs , first graph is correct .
First graph best represents the relationship between kinetic energy and mass.
