Answer :
The magnitude of the force applied by the other worker is 206.0N
What is force?
Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
Force can be push or pull on an object with mass causes it to change its velocity. Force is measured in Newton and it is a scalar quantity.
Force is expressed by the formula;
F = ma
where m is the mass and a is the acceleration.
To calculate the total force on the crate;
F = 0.90 × 430
F = 387N
Therefore the force applied by the other worker
= 387 - 181
= 206.0 N
