Here is your answer:
First find the notations:
5.0×10^2=500.
1.0×10^3=1,000
Then you multiply:
1,000×500=500,000
Your answer is...
=500,000 or 5.0×10^4
Answer:
Length (l) = 6 m
height (h) = 3 m
Load(L) = 500 N
Effort (E) = ?
we know the principal that
E * l = L * h
6 E = 500 * 3
6E = 1500
E = 250
therefore 250 N work is done on the barrel.
I’m trying to get things expanded graph explanation sorry
The resultant force on the system is equivalent to the difference in the weights of the chandelier and Robin Hood.
F(net) = 240g - 85g
F(net) = 155g
Robin Hood's Acceleration:
F = ma
155g = 85a
a = 17.89 m/s²
Tension = mg + ma
Tension = 85(g + a)
Tension = 2400 N
