ssm A person in a kayak starts paddling, and it accelerates from 0 to 0.60 m/s in a distance of 0.41 m. If the combined mass of the person and the kayak is 73 kg, what is the magnitude of the net force acting on the kayak?

Newton's Laws of Motion are three physical laws that, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. These three laws have been expressed in several ways, over nearly three centuries, and can be summarised as follows: In his 1687 "Philosophiæ Naturalis Principia Mathematica" ("Mathematical Principles of Natural Philosophy"), Isaac Newton set out three laws of motion. The first law defines the force F, the second law defines the mass m, and the third law defines the acceleration a. The first law states that if the net force acting upon a body is zero, its velocity will not change; the second law states that the acceleration of a body is proportional to the net force acting upon it, and the third law states that for every action there is an equal and opposite reaction.

In physics, dynamics is the branch of physics concerned with the study of forces and their effect on matter, commonly in the context of motion. In everyday usage, "dynamics" usually refers to a set of laws that describe the motion of bodies under the action of a system of forces. The motion of a body is described by its position and its velocity as the time value varies. The science of dynamics can be subdivided into, Dynamics of a rigid body, which deals with the motion of a rigid body in the frame of reference where it is considered to be a rigid body. Dynamics of a continuum, which deals with the motion of a continuous system, in the frame of reference where the system is considered to be a continuum.

in this question, the person is handling a Qaida and by doing that it goes from a speed off zero meters per second to 0.6 meters per second in a spatial inter haul off 0.41 meters. We have to to know what is the magnitude of the net force that is acting on a kayak. The magnitude of the net force after next is equal. Stupid mask off the kayaks times acceleration of the car we know what is the mass. It's standing treat. So the net force is equals two, 73 times the acceleration. Now how can you discovered acceleration knows that we don't know what is the time interval that it takes for the chi active ill from the zero to be equals to 0.6. But no one is the spatial interval so we can use to retaliate equation To solve this question started charges equation is as follows. The square is because the initial velocity squared two crimes declaration kinds of displacement. Therefore, the final velocity is 0.6 and squared and it goes to the initial velocity which is equal to zero. So you just zero then we have you on the next term, which is true kinds. The acceleration Times X placement off 0.4 to 1. Then we can sew for declaration by standing this term on this term to the other side dividing. So we have that explanation is your question 0.6 square divided by true Pines Euro Coin 41 And this is a question. 0.36 divided by zero corn 82. Then week. Unplugging these acceleration the equation for the net force. And then we get that the net force is egos, too. 73 times 0.36 divided by 0.8 troops and this results in the net force off approximately 32 noodles.
