He was limping along. The world's first electrified road that recharges the batteries of cars and trucks driving on it has been opened in Sweden. Let us now consider banked curves, where the slope of the road helps you negotiate the curve. As opposed to a vehicle riding along a flat circle, inclined edges add an additional force that keeps the vehicle in its path and prevents a car from being "dragged into" or "pushed out of" the circle (or a railroad wheel from moving sideways so as to nearly rub on the wheel flange). A barge of mass 5:0 £ 104 kg is pulled along the Erie Canal by two mules, walking along towpaths parallel to the canal on.
