Energy remains constant is the answer you are looking for but it only applies, when no outside forces act on the object.
Answer:
right A, B, C, D
Explanation:
They ask which statements are true
A) Right. The decrease in amplitude is due to the dissipation of energy by friction and is called damping
B) Right. In resonant processes the amplitude of the oscillation increases, being a forced oscillation
C) Right. In a system with energy loss, the amplitude must decrease, therefore energy must be supplied to compensate for the loss.
D) Right. It is a resonant process the driving force keeps the oscillation of the system
Hello.
h=150 m
u(initial speed)=0
t=5.5 s
<span>v(final speed) =?
</span>
2gh=v^2-u^2
Have a nice day
