G = -10 m/s
s = 0.8 m
v = 0
u = ?
2as = v² - u²
-16 = - u²
u² = 16
u = 4 m/s
Answer:
1404 m
Explanation:
Given that
Depth of ocean = 780 fathoms
Given that
1 fathoms = 1.8 metes
1 fathoms = 1.8 m
Therefore 780 fathoms
1 x 780 fathoms = 1.8 x 780 m
780 fathoms = 1.8 x 780 m
780 fathoms = 1404 m
Therefore the depth of the ocean in meters will be 1404 m.
Note- A fathom is a unit of length equal to 6 feet (1.828 m) in the imperial and U.S. customary systems, especially used to measure water depth in the ocean. In such an imperial fathom there are two yards (6 feet).
From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s
