Answer:
20min = 20 × 60 = 1200sec.
Speed in m per sec.
V = 1000/1200
V = 0.833m per sec.

it is defined as

now we have


Answer:
Option D. 1000 J.
Explanation:
From the question given above, the following data were obtained:
Force (F) applied = 200 N
Distance (s) = 5 m
Time (t) = 10 s
Workdone (Wd) =?
Workdone (Wd) is simply defined as the product of force (F) and distance (s) moved in the direction of the force. Mathematically, it is expressed as:
Wd = F × s
With the above formula, we can calculate the Workdone as illustrated below:
Force (F) applied = 200 N
Distance (s) = 5 m
Workdone (Wd) =?
Wd = F × s
Wd = 200 × 5
Wd = 1000 J
Thus, the Workdone is 1000 J
