How Do Seat Reactions Change with Speed and Acceleration at a 45 Degree Angle?

In summary, the man with a mass of 75 kg is sitting in a chair that is connected to a frame BC. The chair exerts horizontal and vertical reactions on the man, and at the instant theta = 45 degrees, the man has a speed of 6 m/s and is increasing at a rate of 0.5 m/s^2. To solve this problem, you will need to write down all relevant equations of motion and use them to find the horizontal and vertical reactions of the chair on the man.

A man having the mass of 75 kg sits in the chair which
is pin-connected to the frame BC. If the man is always seated in
an upright position, determine the horizontal and vertical
reactions of the chair on the man at the instant theta = 45
degrees

. At this
instant he has a speed of 6 m/s, which is increasing at 0.5 m/s^2

if you can answer this great, but I am looking for someone who can more less give me a step by step to solve this. Thanks for the hlep

Write down all the equations of motion you know that might be useful in solving this.
 

What are dynamics reactant forces?

Dynamics reactant forces are the forces that act on a system or object in motion. These forces can cause changes in the velocity or direction of the object's motion.

What is Newton's Second Law of Motion?

Newton's Second Law of Motion states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. This means that the larger the force acting on an object, the greater its acceleration will be.

How do dynamics reactant forces affect an object's motion?

Dynamics reactant forces can either speed up or slow down an object's motion, depending on the direction and magnitude of the force. They can also change the direction of an object's motion if the force is not acting in the same direction as the motion.

What are some examples of dynamics reactant forces?

Some examples of dynamics reactant forces include friction, air resistance, and gravity. These forces can act on objects in motion and cause changes in their velocity and direction.

How can we calculate dynamics reactant forces?

To calculate dynamics reactant forces, we can use Newton's Second Law of Motion equation: F=ma. This means that the force is equal to the mass of the object multiplied by its acceleration. We can also use various mathematical equations and principles, such as the law of conservation of energy, to calculate these forces.
