A 1030 kg car is pulling a 360 kg trailer. Together, the car and trailer have an acceleration of 2.07 m/s2 directly forward.
How do you find net force on the car and trailer?
the car is pulling the trailer with a net force of F=masstrailer*a
The trailer is pulling back on the car with the same force.
You use Newton's second law,
F = M a
If you want the net force on car and trailer TOGETHER,
F = (1030 + 360)*2.07 N
Note that the weight does not appear. It is balanced by the upward force on the tires.
To find the net force on the car and trailer, you can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
The mass of the car is 1030 kg, and the mass of the trailer is 360 kg. The total mass of the car and trailer combined is therefore 1030 kg + 360 kg = 1390 kg.
The acceleration of the car and trailer together is given as 2.07 m/s².
Now, we can use the formula for net force:
Net force = Mass x Acceleration
Net force = 1390 kg x 2.07 m/s²
Calculating:
Net force = 2871.3 kg*m/s²
So, the net force on the car and trailer is 2871.3 kg*m/s².
