Auniform horizontal rod of mass m and length l rotates with angular velocity ω about a vertical axis through its center. attached to the end of the rod is a small mass m. determine the angular momentum of the system about the axis.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
