Answer:
a) They are the same.
Explanation:
Assuming no friction, there should be no energy transfer and thus the Law of Conservation of Energy says:
These types of problems also disregard any air resistance the surface of the object may cause. Therefore, no energy is transferred and from the Law of Conservation of Energy, of energy is preserved.
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>
