Answer:
<h2>3 kg </h2>
Explanation:
The mass of the ball can be found by using the formula
f is the force
a is the acceleration
We have
We have the final answer as
<h3>3 kg</h3>
Hope this helps you
To find out how much work he has done, we must first calculate force using the force formula (F= Mass*Acceleration). In this case, mass is 79.4 and acceleration is the gravitational constant of 9.8m/s, plugging this into the formula we find that force is 778.12Newtons. Next, we need to multiply force by the distance to get the amount of energy used to lift his partner once. Which is 778.12 * .945 = 735.32. Finally, we need to multiply 735.32 by the number of times he lifts his partner, 33, to get 735.32 * 33 to find that the energy he has expended 24,265.56 Joules of energy.
The change of color. Each color has a different wavelength therefore a different frequency.
