Work is defined as the amount of force done multiplied by the distance it was applied. Since it is already given that the object of interest (a box of groceries) was lifted up 1 meter by a force of 5 newtons, work done can be solved using the following formula:
Work = Force * distance
Work = 5 N * 1 meter
Work = 5 N*m = 5 J

Explanation:
Using the formula;
2x = vt
x is the distance up from the ocean floor the submarine is
v is the speed of sound in water
t is the time
Given
t = 2.3s
v = 1490m/s
Required
how high (approx) up from the ocean floor is the submarine x
From the formula;
x = vt/2
x = 1490(2.3)/2
x = 745(2.3)
x = 1,713.5m
Hence the submarine is 1713.5m high up from the ocean floor
Answer:
0.1m/s²
Explanation:
acceleration =(final velocity - initial velocity)÷time taken
acc=(2-0)÷20
av. acc=0.1m/s²
