A car with a flat top contains a 3.2-cm thick piece of ice lying on its top. Determine how fast this car must travel through still (0?C) air if the piece of ice is to lift off the car. Assume that only the weight of the ice holds it to the car's top and no air flows under the ice while the car is moving.
(a) 15.1 m/s
(b) 17.1 m/s
(c) 19.1 m/s
(d) 21.1 m/s
(e) 23.1 m/s
(f) None of the above.
