Answer:
19,600 Nm
Step-by-step explanation:
WD = mgh
= 40 × 9.8 × 50
= 19600 Nm
W = 19600 N m
W = force * distance
The force is the weight times gravity since it is hanging down
W = 40 kg* 9.8 m/s^2 * 50m
19600 kg m^2/s^2
A newton is kg m/ s^2
the height is 80 m
hope that helps
3
Because if you take 3.4 you round that 4 down to get just 3.
i dont know i am so sorry
