The slope of the velocity time graph of an object moving with constant acceleration is constant
It will take approximately <u>3 seconds</u> for the center of mass of Object X to reach point J near the bottom of the incline
The reason why the above time value is correct is given as follows:
Known parameters:
Initial velocity of the objects, u = 0
The graph in the question is a straight line graph with data points
(0, 0), (0.5, 1.0), (1.0, 2), (3.0, 6), and (3.5, 7)
Given that the slope of the velocity-time graph is constant, we have that the acceleration is constant and is given as follows;

Therefore;

The acceleration, a ≈ 2 m/s²
The distance from the center of mass of the Object X to the point J near the bottom = 9 m
The equation for distance travelled is given as follows;

Which gives;

t = √9 = 3
The time it will take the center of mass of Object X to reach point J near the bottom of the incline is t = <u>3 seconds</u>
