Answer:
v = 16.58 m/s
Explanation:
Given that,
Mass of a bird, m = 1.6 kg
Kinetic energy of the bird, K = 220 J
We need to find the speed of the bird. The formula for the kinetic energy is given by :

Where
v is the speed of the bird
So,

Put all the values,

So, the speed of the bird is equal to 16.58 m/s.
Answer: Energy dissipation
As water passes over a spillway and down the chute, potential energy converts into increasing kinetic energy. Failure to dissipate the water's energy can lead to scouring and erosion at the dam's toe (base).

Answer:
311,850 N
Explanation:
We can solve the problem by using Newton's second law:

where
F is the net force applied on an object
m is the mass of the object
a is its acceleration
For the object in this problem,
m = 27 kg

Substituting, we find the force required:

The latent heat of fusion of water is 344 j/p.This will take 344x300 or 100200 J to melt the ice. once it melted its at oc
