Explanation:
<h3>a) Mass of the continent</h3>
Density is defined as a relation between mass and volume :
(1)
Where:
is the average density of the continent
is the mass of the continent
is the volume of the continent, which can be estimated is we assume it as a a slab of rock 5300 km on a side and 37 km deep:
Finding the mass:
(2)
(3)
(4) This is the mass of the continent
<h3>b) Kinetic energy of the continent</h3>
Kinetic energy is given by the following equation:
(5)
Where:
is the mass of the continent
is the velocity of the continent
(6)
(7) This is the kinetic energy of the continent
<h3>c) Speed of the jogger</h3>
If we have a jogger with mass and the same kinetic energy as that of the continent , we can find its velocity by isolating from (5):
(6)
Finally:
This is the speed of the jogger
