Answer to Question #161273 in Physics for Aila

Question

A bullet moves in an angular direction and its angular velocity w = πt + π in terms of (rad / s) after starting t = 0, its average angular velocity during the time the bullet hits the second round, a few radians per second Is?

Answer 1

The average angular velocity during the time $\Delta t$

$\omega_{avg}=\frac{1}{\Delta t}\int_0^t\omega(t)dt$

Assume that $t=2(s)$

$\omega_{avg}=\frac{1}{2}\int_0^2(\pi t+\pi)dt=\frac{1}{2}\cdot(\frac{\pi\cdot2^2}{2}+2\pi)=2\pi=6.28(rad/s)$ . Answer
