Answer:
27 cm
Explanation:
ASSUMING the elevator is in a constant velocity state (could be zero)
mg = kx
x = mg/k = 15(9.8)/550 = 0.267272... m ≈ 27 cm

Answer:
The wood's potential energy on the carpenter's shoulder is 150 J.
Explanation:
Given;
mass of the wood, m = 10 kg
height through which the wood was raised, h = 1.5 m
acceleration due to gravity, g = 10 m/s²
The wood's potential energy on the carpenter's shoulder is calculated as;
P.E = mgh
P.E = 10 x 10 x 1.5
P.E = 150 J
Therefore, the wood's potential energy on the carpenter's shoulder is 150 J.
The land was frozen everywhere and a part of the ocean froze over to create a bridge between two countries. Some people may disagree with me over the ice bridge, though.
