A scientist claims that people who compete in the Olympic event of skeleton are insane. With their chin often 3 in. from the ice, they rush down the track at speeds of 75 mph on a nearly weightless sled. One turn in the Sochi Olympics had a radius of 50 m. At a speed of 75 mph, calculate the total force on a 145-lb rider. Round the final answer to the nearest whole number.
