Atmospheric drag varies jointly as an object's area \"A\" and velocity \"v\". If a car traveling at a speed of 50 mph with a surface area of 35Ftsquared experiences a drag of 192.5N (Newton’s), how fast must a car with 49ft squared surface area travel in order to experience a drag force of 247.94N?  <BR>\n" );
