A worker is pulling a cart.The frictional force between the cart and the ground is 500N.What is the minimum force that should be applied by the worker .
Answers
500 N is The minimum force that should be applied by the worker.
⦁ Frictional Force is generated by two surfaces that contact and slide against each other.
⦁ By the surface texture and quantity of force requiring them together, these forces are mainly affected.
⦁ The volume of frictional force by the angle and position of the object effect.
⦁ The main reason behind friction between objects appears, known as adhesion, between the points of contact regions of the surfaces.
⦁ From shearing, these 'fused' junction friction arises.
⦁ The frictional force will be the same as the weight of the object.
⦁ Then the frictional force will be increased if an object is pushed against the surface and become extra than the weight of the object.
⦁ If a surface can apply to an object the full amount of friction force can be easily measured.
⦁ The angle and position of the object affect the volume of frictioN= Ffrict = μ Form.
⦁ The resistance to the applied force opposing its motion by frictional force, Thus, it always acts in the direction opposite to that of the object in motion, then friction acts in the right when the force is applied to the left.
Hence, if a worker is pulling a cart, and the frictional force between the cart and the ground is 500N, then 500N is The minimum force that should be applied by the worker.
