Question

if the man pushes with an equal amount of force, which will accelerate more? car because it has less mass lawnmower because it has more mass lawnmower because it has less mass car because it has more mass

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. Rearranging for acceleration gives \(a=\frac{F}{m}\).

Step2: Analyze the effect of mass on acceleration

When the force \(F\) is the same (the man pushes with an equal amount of force), the acceleration \(a\) is inversely proportional to the mass \(m\). That is, a smaller mass \(m\) will result in a larger acceleration \(a\). A lawn - mower has less mass than a car.

Answer:

Lawnmower because it has less mass.
