What is the angular position in radians of the minute hand of a clock at 7:00?
The second hand of a clock is 8.4 centimeters long. Determine the linear speed of the tip of the second hand as it moves through 1 revolution around the clock face (using SI units).
12) The Space X Falcon 9 payload orbits the Earth in 2.5 hours at an altitude of 220 miles. a) Determine the angular speed (in radians per hour) of the payload. b) Determine the linear speed of the payload in miles per hour. Assume that the Earth’s radius is 4000 miles. 11) A clock is running slowly. It takes the second hand of the clock 80 seconds to go all the around instead of 60 seconds. There is point, P,...
