Two workers are working together to push a 430 kg crate off a platform. The crate is experiencing an acceleration of 0.90 m/s2 and the first worker is applying a force of 181 N. Determine the magnitude of the force applied by the other worker (don't worry about direction) and round to one decimal place.

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
