Решение задачи по физике раздел 29 пункт 75 механика

75. Ha edge carriage mass M = 6 kg moving horizontally without friction constant velocity υ = 2 m / s, is lowered to the low height shorter bar mass m = 1 kg. The coefficient of friction between the bar and the carriage f = 0,4. Determine how far s move to the bar of the trolley; the quantity of heat Q at the same time stand out?
