You need it for using the force sensor. Suspend the iolab cart using the string by holding the free end of the string at the edge of a table, so that the iolab cart hangs freely vertically downward. Take a photograph of the set up and paste it below. Next, in the iolab software, select the force" and accelerometer" sensors for your measurements. For accelerometer"s graph, unselect the acceleration in the y and z directions, so that the x direction remains selected. Note that the acceleration in the x direction of the iolab cart corresponds to the tangential acceleration of the pendulum. Pull the cart off to one side and let it swing freely, like a pendulum.

The motion diagram shown in the figure represents a pendulum released from rest at an angle of 45 degrees from the vertical. The dots in the motion diagram represent the position 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 letter of the alphabet.

1. What is the direction of the acceleration of the object at moment 5?

(Enter the letter of the arrow with this direction from the compass rose in the figure. Type Z if the acceleration vector has zero length.)

2. What is the direction of the acceleration of the object at moments 0 and 10?

(Enter the letters corresponding to the arrows with these directions from the compass rose in the figure, separated by commas. Type Z if the acceleration vector has zero length.)
