Zorn and Porsha are ice skating. Porsha has a mass of 60 kg, and Zorn has a mass of 40 kg. As they face each
other, Porsha pushes off Zorn with a force of 168 N. Assume the friction between the skaters and the ice is
negligible.

Assuming the friction between the skaters and the ice is  negligible, the magnitude of Porsha's acceleration is 2.8m/s².

Missing part of the question: determine the magnitude of Porsha's acceleration.

Given the data in the question;

  • Mass of Porsha; [tex]m_{porsha} = 60kg[/tex]
  • Mass of Zorn; [tex]m_{zorn} = 40kg[/tex]
  • Force of Porsha push; [tex]F_{porsha} = 168N[/tex]

Magnitude of Porsha's acceleration; [tex]a = \ ?[/tex]

To determine the magnitude of Porsha's acceleration, we use Newton's second laws of motion:

[tex]F = m*a[/tex]

Where m is the mass of the object and a is the acceleration.

We substitute the mass of Porsha and the force he used into the equation

[tex]168N = 60kg * a\\\\a = \frac{168kg.m/s^2}{60kg}\\\\a = 2.8m/s^2[/tex]

Therefore, assuming the friction between the skaters and the ice is  negligible, the magnitude of Porsha's acceleration is 2.8m/s².
