1. The problem statement, all variables and given/known data The motion diagram shown in the figure represents a pendulum released from rest at an angle of 45 from the vertical. The dots in the motion diagram represent the positions of the pendulum bob at eleven moments separated by equal time intervals. The green arrows represent the average velocity between adjacent dots. Also given is a "compass rose" in which directions are labeled with the letters of the alphabet. Note: The letters in the diagram correspond to the directions. How can I find the direction of the acceleration of the object at moments 0 and 10? 2. Relevant topics Circular Motion Acceleration and direction of object in motion 3. The attempt at a solution First of all, I am having trouble find the velocity of said moments. Can someone help with this?
