Product description
A brick lying on the edge of the roof of a house was pushed up along the slope with a speed v = 10 m/s. After an elastic impact on the ridge, the brick slid back and stopped at the edge of the roof. Determine the coefficient of friction between the brick and the roof surface if the ridge is at a height h = 2.5 m from the edge of the roof. The angle of inclination of the roof to the horizon is a = 30° (Fig.).
