Answer:
A. 350 J
B. 175 W
Explanation:
A. Determination of the work done.
Force (F) = 50 N
Distance (s) = 7 m
Workdone (Wd) =?
Work done = force × distance
Wd = F × s
Wd = 50 × 7
Wd = 350 J
Therefore, the Workdone is 350 J
B. Determination of the power.
Work done (Wd) = 350 J
Time (t) = 2 s
Power (P) =?
Power = Work done / time
P = Wd / t
P = 350 / 2
P = 175 W
Therefore, the power is 175 W
