Answer:
Mechanical energy, U = 0.247 Joules
Explanation:
Given that,
Spring constant of the spring, k = 234 N/m
Mass, m = 524 g = 0.524 kg
Amplitude, A = 4.6 cm = 0.046 m
To find,
The mechanical energy of the system.
Solution,
We know that the sum of kinetic energy and the potential energy is equal to its mechanical energy. In mass-spring system, it is given by :


U = 0.247 Joules
So, the mechanical energy of the system is 0.247 Joules.
I would say C: Dam
Sea walls and levees stop water from overflowing onto something. Which can we good but has no impact on droughts.
Storm shelters wont impact droughts either. They are men't to protect people from storms.
A Dam on the other hand can contain and keep water in one given place. Which will save water, to be used to prevent future droughts.
Hope this helps!
Brainliest is appreciated if you feel its deserved!
Answer:

Explanation:
= Mass of Bonzo
= Mass of Ender
= Initial Velocity of Bonzo = 2.2 m/s
= Initial Velocity of Ender = -2.6 m/s
From conservation of linear momentum
