Question

A 650 kg car pulling the a 475 kg traileraccelerates forwardat a rate of 2.27 m/s .Assume the frictinal force on the trailer are neglgibale

Calculste the net fotce (in N) on the car.

Answer 1

The net force on a car pulling a trailer with a combined mass of 1125 kg and accelerating at 2.27 m/s^2 is 2553.75 N, calculated using Newton's second law (F = ma).

Step-by-step explanation:

To calculate the net force on a car pulling a trailer, we 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 (F = ma).

The mass of the car is 650 kg, the mass of the trailer is 475 kg, and the acceleration is 2.27 m/s2. The combined mass of the car and the trailer is the sum of the individual masses.

• Calculate total mass: 650 kg (car) + 475 kg (trailer) = 1125 kg
• Calculate net force: Net force = total mass × acceleration = 1125 kg × 2.27 m/s2 = 2553.75 N

The net force required to accelerate both the car and the trailer is 2553.75 N.
