In this problem, you are asked to find a vertical position of a ball when you are given its initial position on a spring. In both locations, the speed of the ball is zero.
If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points, conservation of energy is the most direct way to understand the problem.
In this case, you start out with stored energy in the compression of the spring and convert it to stored gravitational energy.
Answer:
Displacement CO=2.15 Km
Average velocity = 1.99 Km/h
Explanation:
Given
Total time = 1.08 h
OA= 1.62 Km
AB=0.246 Km
BC=3.08 Km
θ=50.4°
CE=3.08 sin50.4° =2.37 Km
BE=3.08 cos50.4° =1.96 Km
CE=AB+OD
OD=CE-AB
OD=2.37-0.246
OD=2.124 Km
BE=CD+OA
CD=BE-OA
CD=1.96-1.62
CD=0.34 Km
Now CO
CO=2.15 Km
So the displacement CO=2.15 Km
Average velocity =Displacement/Time
Average velocity = 2.15/1.08 Km/h
Average velocity = 1.99 Km/h
Answer:
Explanation:
the development of the history of science, the histories of the individual scientific disciplines have played an enormously significant role. The goals and functions of these have recently received considerable attention, both because of the influence that such histories have had on the legitimacy and self-image of the disciplines and also because of the adaptability that they have shown when faced with the conceptual and methodological changes that they have undergone.
