How to Calculate Forces in Motion

What are the net forces acting on the car and trailer in motion?

(a) the net force on the car
_______N
(b) the net force on the trailer
_______N
(c) the force exerted by the trailer on the car
________N
(d) the resultant force exerted by the car on the road
magnitude _______ N
direction _________

Answer:

The net force on the car is 2060N, and the net force on the trailer is 570N.

Understanding Forces in Motion

When an object interacts with another object, there is a push or pull applied to the object. An item can accelerate, change direction, or remain in the same location as a result of forces.

Calculating Forces

(a) By utilizing the equation F=ma, where m is the car's mass and a represents its acceleration, one may calculate the net force acting on the vehicle.

F=(1.030 kg X 2.00 m/s2) = 2060 N

(b) The equation F=ma, where m is the mass of the trailer and a is the acceleration, can also be used to calculate the net force on the trailer.

570 N is equal to F = (285 kg X 2.00 m/s2).

(c) The force the automobile exerts on the trailer is equal to and opposing the force the trailer exerts on the car. The trailer pulls on the car with a force of -570 N since they are going in the same direction.

(d) The force the car exerts on the road is 2060 N since the net force acting on the car is 2060 N.

2060 N in a forward-moving direction (positive x-direction)
