Question

A 2.6 kg mass attached to a light string rotates on a horizontal,

Answer 1

The maximum speed the mass can have before it breaks is 2.27 m/s.

The given parameters:

• maximum mass the string can support before breaking, m = 17.9 kg
• radius of the circle, r = 0.525 m

The maximum speed the mass can have before it breaks is calculated as follows;

$T = ma_c\\\\Mg = \frac{Mv^2}{r} \\\\v^2 = rg\\\\v = \sqrt{rg} \\\\v_{max} = \sqrt{0.525 \times 9.8} \\\\v_{max} = 2.27 \ m/s$

Thus, the maximum speed the mass can have before it breaks is 2.27 m/s.
