1. (a)The speed of the tip of the minute hand on a
town clock is 0.00136 m/s.
What is the speed of the tip of the second
hand of the same length?
Answer in units of m/s.
(b)What is the centripetal acceleration of the tip
of the second hand?
Answer in units of m/s2.
atotal = sq rt (a2 radial + a2 tangential) where aradial = −v2/r and atangential = d|v|/dt
I have no idea how to start this... I just think I need to use those equations
