Answer:
t=0.58s
Explanation:
We can consider only the horizontal component since the horizontal component of the velocity is constant (
), and we want to know how much time it takes for the balloon to travel a horizontal distance
at that speed. The definition of (horizontal) velocity is
, so we have:

I wish i could help with this one
Answer:
The total mechanical energy of a simple harmonic oscillating system is Constant
Explanation:
During the movement of an object in simple harmonic motion, the total mechanical energy is constant
The total mechanical energy is given by 
By the conservation of energy principle the energy in the simple harmonic motion transforms between kinetic and potential energy while maintaining a constant sum
