A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of $+11 \mathrm{m} / \mathrm{s}$ in a time of 28 $\mathrm{s}$ . The combined mass of the boat and trailer is 410 $\mathrm{kg}$ . The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car?

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.

to solve this question, you can apply Newton's second law to the boat Andi the trailer together. So you by doing there to get the following the net force acting on them. Is it close to the complainant? Mass times their acceleration. So the net force has only one component on the horizontal direction, which is the direction we are interested. So let me say that everything that is pointing to the right is pointing to the positive direction them. There is only attention force pointing in that direction. Let me call this X truth, then the station force is because they combine it mass 410 times acceleration off them. But they're acceleration isn't even, but we can calculate it by using the following equation. Acceleration is given by the variation in the velocity divided by the time it took in the situation. We have 11 meters per second, divided by 28 seconds. Then the tension force is 410 times 11 divided by 28. These results in attention force off approximately 160 new palace
