Question

multiple choice question
the illustration represents the force on, and acceleration of, vehicles with different masses.
suppose that the force on the vehicles is the same. according to newtons second law of motion, how will the acceleration of the two vehicles compare?
o the acceleration of the car will be greater.
o there is not enough information to tell.
o the acceleration of the truck will be greater.
o their acceleration will be the same.

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). If \(F\) is constant, then \(a=\frac{F}{m}\), which means acceleration is inversely proportional to mass.

Step2: Compare the masses of the car and the truck

The mass of the car \(m_{car}=900\space kg\), and the mass of the truck \(m_{truck} = 1200\space kg\). Since \(m_{car}

Answer:

The acceleration of the car will be greater.
