3 Minutes If BJ and Pete are flying an airplane that weighs 62,500 pounds fully loaded, then they must generate 62,500 pounds of lift to fly. The flight path requires an altitude of 20,000 feet and a cruising speed of 375 knots to conserve fuel. The aircraft wing area is 750 square feet. In order to find the CL for the plane, convert 375 knots to feet per second. Choose the correct expression to convert 375 knots to feet per second. Round to the nearest tenth.HINT: 1 knot = 6,076 feet per hour; 1 hour = 60 x 60 = 3600 seconds. A) (3600 x 375)/6076 = 222.2 feet per secondB) (6076 x 375)/3600 = 632.9 feet per secondC) (3600 x 6076)/375 = 58329.6 feet per secondD) 6076/375 = 16.2 feet per second |
