Question

A girl with a mass of 27 kg is playing on a swing. There are three main forces

Answer 1

The tension in the swing's chain at the bottom of the swing is 178.35 N.

The given parameters:

• Mass of the girl, m = 27 kg
• Speed of the girl, v = 3 m/s
• Radius of the circle, r = 4 m

The tension in the swing's chain at the bottom of the swing is calculated as follows;

$T = mg + ma_c\\\\ T= mg + \frac{mv^2}{r} \\\\T = (12 \times 9.8) + (\frac{27 \times 3^2}{4} )\\\\T = 117.6 \ N \ + \ 60.75 \ N\\\\T = 178.35 \ N$

Thus, the tension in the swing's chain at the bottom of the swing is 178.35 N.
