Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.

Help me solve the following table. Angle of incidence (?i) is 65, angle uncertainty (??) is 1. I tried (1*2.4919*pi)/180 * ((1/tan65)+(1/tan22)) = ?n, but it said the answer was wrong, and i don't know how to continue from there. So, the answer cannot be 4.8838.
nework @@ 2 W S Question 9 of 14 X mmand Your answer is partially correct. A person is standing at the edge of the water and looking out at the ocean (see figure).

1. A student runs to school, covering a distance of 0.50 km in a direction of [N20^0 E] as measured from the starting point. She then trudges over to a friend's house 0.30 km away [W] from the school. The two friends then go off to the mall that is 0.8 km [W50^0S] from the friend's house. *You will need to draw the x and y components of the vectors a. What is the total displacement of the student? b. If the total time taken by the student to run to school then trudge over to the friend's house was 25 minutes, what was her average velocity? *There are many steps to this answer, ensure that you have included ALL steps.
