For the tip of the second hand, calculate the.... a) Displacement vector in unit vector notation. b) Average velocity vector in unit vector notation c) Average acceleration vector in unit vector notation d) Calculate the magnitude and direction of Average Acceleration
A wall clock has a minute hand with a length of 0.53 m and an hour hand with a length of 0.23 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. Find the displacements of the tip of each hand (that is, ΔA with arrow and ΔB with arrow) when the time advances from 3:00...
