1. The problem statement, all variables and given/known data What are a) average velocity and b) average acceleration of the tip of the 2.4cm long hour hand clock in the interval from noon to 6pm. Use unit vector to express, wth the x axis pointing towards 3 an y axis towards noon. 2. Relevant equations 3. The attempt at a solution V = deposition/dt P2 = -2.4j P1= 2.5j P2-p1 = -4.8 -4.8e-3/21600= -2.22e-6j b) can I have a leg up? I know a = dv/dt but I can't build a mental geometrical set up.
