The angle between the ball's initial velocity vector and the wall is 6 as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is At, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the wall is parallel to the x axis. What is the final angle Of that the ball's velocity vector makes with the negative y axis?

Needs Complete solution with 100 % accuracy don't use chat gpt or ai please plz plz plz plz.

Please explain the answers in easy to understand way. What can you say about the accuracy of your measurements? What can you say about the precision of your measurements? Measure the longest dimension of the room twice, using two different techniques. Do the measurement in feet and inches. Then convert to meters. Below is what I got. Tape Measure - 146 inches > 3.7084 meters / 12 feet and 2 inches = 12.1667 feet > 3.70840 meters  Ruler - 144.5 inches (144 + 1/2) = 3.6703 meters / 12.0416 feet = 3.67027 meters
