Answer:
131.09828 Joules
Explanation:
u = Initial velocity of the ball = 0
v = Final velocity of the ball when the batter makes contact with the ball= 42.91 m/s
m = Mass of the baseball = 0.1424 kg
Kinetic energy
The kinetic energy the ball has is 131.09828 Joules
The distance between two succesive crests of a wave corresponds to its wavelength, therefore the wavelength of this wave is
The frequency of a wave is the number of crests that passes through a given point in a certain time; therefore, for this wave it is:
And now we can calculate the wave speed, which is given by the product between the wavelength and the frequency:
