Hi all,
I'm having a very difficult time with this problem. I know that the magnitude stays the same and it involves uniform circular motion, but I just can't seem to figure out how to begin the problem or what formula to use. I would really appreciate any kind of help.
A wall clock has a minute hand with a length of 0.47 m and an hour hand with a length of 0.24 m. Take the center of the clock as the origin, and use a Cartesian coordinate system with the positive x-axis pointing to 3 o'clock and the positive y-axis pointing to 12 o'clock. What is the magnitude of the acceleration of the tip of the minute hand of the clock?
I also need to express it as a fraction of the magnitude of free-fall acceleration g.
Again thank you all very much, any kind of help would be so much help.
