Gravity of the earth = 9.78 m/s² and frictional force due to air
Answer:
D
Explanation:
gaseous water moves from the atmosphere to earths rivers and oceans
The greater the speed of two identical masses, the greater the kinetic energy. So, the mass that is traveling twice as fast as the other has much more kinetic energy. The formula for kinetic energy is KE=m*v^2 (kinetic energy equals mass times velocity squared), and velocity is the same as speed in this case because it is squared. So, the mass traveling twice as fast has 4 times the kinetic energy, because 2 squared=2*2=4.
Answer: The mass traveling twice as fast has four times the kinetic energy.
