You've got a 69.0-kg wooden crate on a wooden floor. The box can withstand a force of up to 338N in a horizontal direction without being moved. Following this, the wooden creates moving stats.
In order to calculate the friction coefficient, divide the force pushing two objects together by the force acting between them. friction coefficient might be 0 or one. They can be split into two categories: friction coefficient that is static. Kinetic friction coefficient (also known as sliding coefficient of friction).
the acceleration brought on by the gravitational pull of large masses generally, gravitational , often known as the acceleration brought on by the Earth's gravitational pull and centrifugal force,
F= friction coefficient *M*g
F= 0.5*69*9.8
F=338N

Hello!
Answer: 7918 J
Explanation:
We are assuming that the floor (field) is completely horizontal since there's no information about that in the statement.
We are going to use the following formula:
Where:
º
Then, by substituting we have:
Yo sup??
The weight vector is usually drawn vertically downwards from the centre of the body.
It can be respectively resolved as well.
Hope this helps
Answer:
Friction
Explanation:
The key and most important external forces that allows a man to push a wheelbarrow is frictional force.
Frictional force is a force that opposes motion and will bring it to a halt.
The reason why motion is possible is due to frictional force.
Without friction, a body will move and continue in motion infinitely. No one will be able to control motion.
- Therefore, frictional force is an external force that will allow a man to push a wheelbarrow.
