A girl pulls a loaded sled with mass m = 40 kg on some horizontal snowy pavement with 115 N of force. The velocity of the sled is constant. The coefficient of kinetic friction μk between the runner and the pavement is 0.3 and the angle θ between the cord and the pavement is 20°. Find the magnitude of the normal force by which the sled affects the pavement. Find the magnitude of the friction force that affects the sled.
