A20.0 kg curling stone travels 30.0 m along the ice surface. if the frictional force is 10.0 n, the thermal energy produced is

thermal energy is 300 J

Explanation:

Thermal energy produced while moving on the rough floor is same as the work done by friction force

because friction force is a non conservative force which will produce thermal energy in the form of energy loss

so here this thermal energy is given by

here we have

so the work done is given by

So the thermal energy is 300 J
