The centripetal force experienced by the towel is 55 N.
The given parameters;
- angular speed of the washing machine, ω = 200 rpm
- radius of the machine' drum, r = 0.5 m
- mass of the towel, m = 0.25 kg
The centripetal force experienced by the towel spinning along the walls of the drum is calculated as follows;
Fc = mrω²
where;
<em>Fc is the centripetal force</em>
<em>ω is angular speed in rad/s</em>
The angular speed in rad/s is calculate as;
The centripetal force experienced by the towel is calculated as;
Thus, the centripetal force experienced by the towel is 55 N.
