meters of the curved section frictionless. Cal- culate the speed v of a car which can cross this Question 12 frictionless section without slipping sideways. part 1 of 1 10 points Answer in units of m/s. Calculate the average speed of the Moon Question 10 around the Earth. The Moon has a period of revolution of 27.3 days and an average dis- part 1 of 1 10 points tance from the Earth of 3.84 x 108 m. A dragster maintains a speedometer read- ing of 100 km/h and passes through a curve 1. 2045.8 m/s with a constant radius. 2. None of these 3. 8.83789 x 10' m/s 4. 3688.5 m/s 5. 3.68245 x 10 m/s 6. 2054.6 m/s 7. 584000 m/s With which of the following statements do you agree. 8. 1022.9 m/s 1. The dragster ran along a line at a constant 9. 61374.2 m/s velocity of 100 km/h. Question 13 2. The dragster rounded the curve at a part 1 of 1 10 points changing speed of 100 km/h. What is the frequency of the minute hand 3. The dragster rounded the curve at a con- of a clock? T= 60 min stant velocity of 100 km/h. 1. 24 Hz = 60 x 6 05 4. All are wrong. = 3600S 2. 0.0000116 Hz f = = 3406 Hz 5. The dragster rounded the curve at a changing velocity of 100 km/h. 3. 1 Hz
