There is no air resistance on the moon, so when Neil Armstrong dropped a

hammer all of the potential energy turned into kinetic energy. If Neil was 12

feet tall instead of 6 feet, would the hammer be moving faster or slower

just before hitting the ground? Why?

Sagot :

Answer: faster

Explanation:

Given

hammer is dropped from a height of  12 ft on the surface of the moon

Here, the potential energy is converted into kinetic energy

[tex]\Rightarrow mgh=\dfrac{1}{2}mv^2\\\\\Rightarrow v=\sqrt{2gh}[/tex]

That is velocity is a function of the square root of height. The more the height, greater is the velocity.  

So, the hammer hits the ground faster .
