three boxes connected by strings.
given the mass of each box, coefficient of static and kinetic friction, and a constant speed of 2.0 m/s
I want to know how to get force by a given speed...!
Also, at a constant speed, how do I get to know the acceleration? does a = 0? if a = 0, how can I find Forces?Homework Equations
F = ma
The Attempt at a Solution
Newton's law of motion is a physical law that describes the relationship between an object's mass, acceleration, and the force acting upon it. It states that an object will remain at rest or continue moving at a constant velocity unless acted upon by an external force.
In the context of crates and strings, Newton's law of motion applies to the relationship between the force applied to the crate and its resulting acceleration. For example, if a string is used to pull a crate, the force applied to the crate through the string will cause the crate to accelerate in the direction of the force.
Friction is a force that opposes motion and is an important factor in Newton's law of motion. In the context of crates and strings, friction between the string and the surface may reduce the acceleration of the crate. Additionally, friction between the crate and the surface it is resting on may also affect its movement.
The three laws of motion according to Newton's law of motion are:
Crates and strings can illustrate Newton's first law of motion by showing how an object will remain at rest or in motion unless acted upon by an external force. For example, if a crate is at rest and no external force is applied to it, it will remain at rest. However, if a string is used to pull the crate, an external force is applied and the crate will begin to move in the direction of the force.
