Answer:

Duck's kinetic energy is 64.8 Joules

Explanation:

It is given that,

Mass of the duck, m = 0.9 kg

Velocity of the duck is, v = 12 m/s

We have to find the velocity of the duck. It is given due to the motion of an object. Mathematically, it is written as :

KE=\dfrac{1}{2}mv^2

KE=\dfrac{1}{2}\times 0.9\ kg\times (12\ m/s)^2

KE = 64.8 Joules

Hence, the kinetic energy of the duck is 64.8 Joules

It should be at about 65J. Not sure, hope I helped.

How does energy from an earthquake reach each surface? Describe the three types of seismic waves.
WITCHER [35]
Body waves travel through the interior of the Earth. Surface waves travel across the surface. Surface waves decay more slowly with distance than body waves which travel in three dimensions. Particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage.

Anastasy [175]

a) In this case the forces are the centrifugal force Fcp, which is directed horizontally toward the wall; the force of static friction Ff with the wall, directed upward; the normal force Fn by the wall, which is directed away the wall; the force of gravity Fg, directed downwards. Then we have that the horizontal forces are all equal in magnitude; similarly the vertical forces are also all equal in magnitude.

 

b) The minimum coefficient s occurs when force of gravity is equals the max friction force, that is

Fg = Ff,max

m g = s Fn

 

Also, the normal force has equal magnitude to the centrifugal force:

m g = s Fcp

m g = s m w^2 r

g = s w^2 r

s = g / (r w^2)

 

With values: g = 9.81 m/s^2; r = 2.5 m; and w = 2pi * 0.60 = 3.77 rad/s; we find

 

s = 9.81 / (2.5 * 3.77^2) = 0.276
