Question

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?

Answer 1

Answer: faster

Step-by-step 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

`\Rightarrow mgh=(1)/(2)mv^2\\\\\Rightarrow v=√(2gh)`

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 .
