False.
The mass of a softball is approximately 200 g (0.2 kg), while the knees are located approximately at 30 cm (0.3 m) from the ground. It means that the gravitational potential energy of the ball when it is dropped is
This corresponds to the total mechanical energy of the ball at the moment it is dropped, because there is no kinetic energy (the ball starts from rest). Then the ball is dropped, and just before it hits the ground, all this energy is converted into kinetic energy: but energy cannot be created, so its final kinetic energy cannot be greater than 0.6 J.
Answer:
Option B is correct.
Explanation:
Given data
Height of the hill = AB = 1 m
Distance traveled along the rough bottom surface = AC = 2 m
Now from the ΔABC
°
We know that the coefficient of kinetic friction is
0.5
This is the value of the coefficient of kinetic friction
Thus option B is correct.
The frequency of the wave is 0.5Hertz
<h3>How to calculate the
frequency of a wave</h3>
The formula for calculating the velocity of a wave is expressed as:
velocity = frequency * wavelength
Determine the formula for the frequency
frequency = velocity/wavelength
Given the following parameters
Velocity = 1.00 m/s
wavelength = 2.00m
Determine the frequency
f = 1.00/2.00
f = 0.5Hz
Hence the frequency of the wave is 0.5Hertz
