Explanation:
2,450 Joules, kinetic energy is 1/2 mass x velocity squared.
Answer:
1.75 m/s
Explanation:
k = Spring constant = 490 N/m
m = Mass of object = 5.8 kg
x = Displacement of spring = 0.19 m
v = Speed of object at the equilibrium position
The potential energy of the spring will balance the kinetic energy of the mass
The speed of the mass as it returns to the equilibrium position is 1.75 m/s.
