Homework Statement
The speed of the tip of the minute hand on a
town clock is 0.00182 m/s.
What is the speed of the tip of the second
hand of the same length?
Answer in units of m/s.
What is the centripetal acceleration of the tip
of the second hand?
Answer in units of m/s2.
Homework Equations
ac=4pi2r/T2
The Attempt at a Solution
Ok to find the speed of the second, I multiplied by 60 and got .1092 m/s
for the acceleration I'm not given r, so I need to find r using this equation, V=2pi r/T
I was wondering what id T ? is it 60 seconds ? Thank you
