Question

1. what is the net force acting on a 1.0 - kg ball moving at a constant velocity?

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is the net force, \(m\) is the mass, and \(a\) is the acceleration.

Step2: Determine the acceleration

When an object is moving at a constant velocity, its acceleration \(a = 0\) (since acceleration is the rate of change of velocity, and if velocity \(v\) is constant, \(\frac{\Delta v}{\Delta t}=0\)).

Step3: Calculate the net force

Substitute \(a = 0\) and \(m = 1.0\space kg\) into \(F=ma\). So \(F=(1.0\space kg)\times(0)=0\space N\).

Answer:

\(0\space N\)
