What is your c= √(a^2+b^2-2abcos°)? You need the sum of the two forces, but you calculated the difference.Kmcquiggan said:
That looks better.Kmcquiggan said:
?? Why are you using the sine law?Kmcquiggan said:
Looks OK. As does the rest of your work.Kmcquiggan said:
Newton's Laws of Motion are three fundamental principles of physics that describe the behavior of objects in motion. 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 remain in motion at a constant velocity 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 it and inversely proportional to its mass. This can be mathematically expressed as F=ma, where F is the net force, m is the mass, and a is the 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 exerts an equal and opposite force back on the first object.
Newton's Laws of Motion are used in many aspects of everyday life, from driving a car to playing sports. They help us understand the behavior of objects in motion and allow us to make predictions and calculations about the motion of objects. For example, understanding the Second Law of Motion can help us calculate the force needed to move a heavy object, while the Third Law of Motion explains why we feel a force when we push against a wall.
