Question

A metal block rests on a rough horizontal surface on the Earth. A horizontal force of 20 N is required to start the block moving. An identical block rests o identical surface on the Moon where gmoon 1.60 m s². Determine force required to start to the block on the Moon moving. Illustrate the fo acting on the two blocks. n an the horizontal rces

Answer 1

To determine the force required to start the block on the Moon moving, divide the force required on Earth by the acceleration due to gravity and multiply by the acceleration due to gravity on the Moon, we get 3.26 N.

Step-by-step explanation:

To determine the force required to start the block on the Moon moving, we can use the equation F = ma, where F is the force, m is the mass of the block, and a is the acceleration. On Earth, the acceleration due to gravity (g) is 9.8 m/s², while on the Moon, the acceleration due to gravity (gmoon) is 1.60 m/s².

First, we need to calculate the mass of the block by dividing the force required to start it moving on Earth by the acceleration due to gravity:

m = F/g

= 20 N / 9.8 m/s²

= 2.04 kg.

Next, we can calculate the force required to start the block on the Moon moving by multiplying the mass of the block by the acceleration due to gravity on the Moon:

Fmoon = m * gmoon

= 2.04 kg * 1.60 m/s²

= 3.26 N.
