1. A race car at Daytona 500 travels at a constant speed of 13.4 m/s on an inclined, circular turn of radius 50.0m, as shown in the figure below. What minimum coefficient of static, friction between the tires and the roadway will allow the car to make the circular turn without sliding? (a) 0.260 (b) 0.0385 (c) 0.101 (d) 0.00250 CAR INCLINE JO =20.0° REAR VIEW OF THE CAR 2. A meteorite is orbiting around the Earth. The shortest distance and longest distance of the orbit from the center of the Earth are 1.50 x 10% m, 4.77 x 10% m, respectively. If the meteorite has a speed of 1.78 x 10° m/s when it is at the location of the shortest distance from the Earth, the speed of the meteorite at the location of the longest distance from the Earth is (a) 1.66 x 10° m/s (b) 1.03 x 105 m/s (c) 5.60 x 10° m/s (d) 7.43 x 107 m/s 3. A construction worker with mass m = 55.0 kg stands 2.00 m away from the wall on a 6.00-m, homogeneous, uniform beam, as shown in the figure below. The mass of the beam is 40.0 kg. The force exerted on the beam by the wall has the following components: (a) Rx = -445 N; Ry = 871 N beam cable (b) Rx = -650 N; Ry = 556 N %3D (c) Rx = 347 N; Ry = 108 N (d) Rx = 508 N; Ry = -678 N I 30.0° A 2.00m 6.00m-
