The time for the echo to return is directly proportional to the distance. vw = fλ. In a given medium under fixed conditions, vw is constant, so that there is a relationship between f and λ; the higher the frequency, the smaller the wavelength.
Distance of first instance = speed * Time
= 60 * 3 = 180 miles
Distance of second instance = speed * Time
= 24 * 5 = 120 miles
So, Total Distance = 180 + 120 = 300 miles
In short, Your Answer would be 300 miles
Hope this helps!
Answer:

Given
mass of baseball
radius of ball
angular speed of ball
linear speed of ball
Transnational Kinetic Energy is given by
Considering the ball as solid sphere its moment of inertia is given by
Rotational Kinetic Energy
40kg
Explanation:
Given parameters:
Kinetic energy = 500J
Velocity = 5m/s
Unknown:
Mass of the object = ?
Solution:
Kinetic energy is the energy due to motion of a body. It is expressed as:
K.E = mv²
m is the mass of the body
v is the velocity
To find the mass, make it the subject of the expression:
m = }[/tex]
m = }[/tex] = 40kg
