Answer:
a) v = 4.4 m/s
b) F = 400 N
Explanation:
a) ½kx² = ½mv²
v = √(kx²/m)
F = kx
v = √(Fx/m)
v = √(800(0.012) / 0.5) = √19.2 = 4.3817...
b) Fd = ½mv²
F = mv²/2d
F = 0.5(19.2) / (2(0.012) = 400 N
Answer:
Bernoulli
Explanation:
Hello! I took the k12 science quiz! I hope you get an A!
Have a blessed day! :)
The frequency at which the body vibrates breaks is natural frequency. The glass with her voice because the frequency of her voice matches the natural frequency of the glass.
<h3>What is the natural frequency?</h3>
When there is no external force acting on the body unless the body vibrates is known as the natural frequency of vibration.it is denoted by
.
when the frequency of a body matches the natural frequency a condition occurs known as resonance.
To learn more about the natural frequency refer to the link;

Answer:
As You know kinetic Energy is equal (mv^2)/2
You can increase it by increasing the mass(keeping the velocity)
Or You can add velocity
