Answer:
0.1164 m
0.49387 m
Explanation:
m = Mass = 5 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height from which brick falls = 12 m
k = Spring constant = 8 kN/m
a) Potential energy of the brick
Potential energy in spring
The compression of spring = 0.5-0.3836 = 0.1164 m
b) Weight of the brick
The final length of the spring = 0.5-0.00613 = 0.49387 m
