Answer:
Submarine W. the closest submarine is the one with the lowest depth, -1.5 km (which should actually be written as an absolute value, 1.5km, depth can't be negative).
The time taken for the particle to travel more than 8 meters from the point of projection is 0.59 s.
<h3>
Time of motion of the particle</h3>
The time taken for the particle to travel more than 8 meters from the point of projection is calculated as follows;
s = v₀t + ¹/₂at²
8 = 12t + (0.5 x 5)t²
8 = 12t + 2.5t²
2.5t² + 12t - 8 = 0
solve the equation using formula method
t = 0.59 s
Thus, the time taken for the particle to travel more than 8 meters from the point of projection is 0.59 s.
