The Attempt at a Solution
I don't know what I'm doing wrong, but I'm not getting the correct answer of 17cm ...
whoareyou said:23.52N (the reaction force from the friction of block A) = ma
Now I assumed that it was the total mass of the system, since block A is on top of it and its moving with it. Was that assumption wrong?
23.52N = (m1 + m2)a
a = 23.52 / (m1+m2) = 23.52 / (4 +1 ) = 4.704m/s^2
Newton's Laws of Motion are three physical laws that describe the relationship between the motion of an object and the forces acting upon it. They were first described by Sir Isaac Newton in his book "Philosophiæ Naturalis Principia Mathematica" in 1687.
The first law of motion, also known as the Law of Inertia, states that an object at rest will remain at rest and an object in motion will continue in a straight line at a constant speed unless acted upon by an external force.
The second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. This can be mathematically expressed as F=ma, where F is force, m is mass, and a is acceleration.
The third law of motion, also known as the Law of Action and Reaction, states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object will exert an equal and opposite force back onto the first object.
To solve problems using Newton's Laws, you first need to identify the forces acting on the object and their directions. Then, you can use the equations derived from the laws to calculate the acceleration, velocity, or force of the object. It is important to carefully consider all forces and their directions in order to accurately apply the laws and solve the problem.
