Answer:
(i) , (ii)
, (iii)
Explanation:
(i) and
represent the points where particle has a velocity of zero and spring reach maximum deformation, Given the absence of non-conservative force and by the Principle of Energy Conservation, the position where particle is at maximum speed is average of both extreme positions:
(ii) Maximum accelerations is reached at and
.
(iii) Greatest net forces exerted on the particle are reached at and
.
To solve this problem it is necessary to apply the concepts related to Newton's second Law and its definition of density.
By Newton's second law we understand that,
F = ma
Where,
m = mass
a = acceleration (at this case the gravity acceleration)
In the case of density, we know that it is described as the proportion of mass versus volume, that is,
Where,
m = mass
V = Volume
The total tension of the AB cable would be given by the tension exerted upwards by the water and the tension exerted by the weight, therefore,
Mass can be expressed as,
Therefore the tension in cable AB is 6103.94N
