Answer: a)2040N b) 310N
Step-by-step explanation
Force is defined as an external agency that causes a body to accelerate or change its position. Therefore the formula for acceleration is given by Force = mass of the body × acceleration.
Applying this formula to the given question
a)The net force on the car will then be F = 1020 ×2 which gives 2040N (mass of the car being 1020kg)
b)The net force on the trailer will then be F = 310 ×2 which gives 620N (mass of the trailer being 310kg)
