Analysis Questions: All Calculations Below 1. Use the velocity components to determine the direction of the velocity vector. Is it in the expected direction?   The angular velocity from video analysis is 2.75 rad/s. The linear velocity (calculation below) for 6, 12, 18 cm is 0.17 m/s, 0.33 m/s, and 0.50 m/s. The direction of the linear velocity is tangent to the circular path the beam takes which is expected 2. Analyze enough different points in the same video to make a graph of the speed of a point as a function of distance from the axis of rotation. What quantity does the slope of this graph represent? We used a cosine graph for the fit and the average slope of the three radiii was 2.75 rad/s and this represents the angular velocity.   The way we made sure that the value of the angular velocity was the same for the three radii was by using the same video and letting the beam make 2 revolutions. 3. Calculate the acceleration of each point and graph the acceleration as a funct...
