Answer:
87.5 m/s
Explanation:
The speed of a wave is given by

where
v is the wave speed
is the wavelength
f is the frequency
In this problem, we have
is the frequency
is the wavelength
Substituting into the equation, we find

The force the horse and the rider exerts on the wall is equal to the weight combined acting in the opposite direction:
<h3>Force</h3>
Given Data
- mass of horse and rider = 575kg
- Force acting on wall = ??
When a body of mass rests on a surface, it exerts a force equal to the weight of the mass but opposite in direct on the mass/object
hence the force is computed as
Force = mass * acceleration
Force = 575 * 9.81
Force = 5640.75N
