Задача id10419

A body slides down an inclined plane with a length of 260 m and an angle of inclination of 60°. The coefficient of friction on the plane is 0.2. Determine how many degrees the body temperature will increase if 50% of the heat released is used to warm it. The specific heat capacity of the material from which the body is made is 130 J/(kg*K), g = 10 m/s2.
