F=MA
F + 200= 250 x 4
F + 200 = 1000
F= 1000-200
F= 800
Answer: his total speed would be 3 seconds
Explanation: because if you mulimply 10 x 3 you get 30 meaning that your answer would be 3
For this case, the relationship between the two forces is given by:
F1 = nF2
Where,
- F1: output strength
- F2: input force
- n: mechanical advantage
Then, replacing the values we have:
F1 = (2.2)(202)
Having the calculations we have:
F1 = 444.4N
Answer: The output force that only lifts the load is F1 = 444.4N.
Power is equal to the rate of energy usage, or work over time (W/t). It could also be consider Fd/t, since W=Fd.
