Question 2

0.5 pts

The turret shown rotates w.r.t. the ground

about the y axis at a constant 12rad/s.

Simultaneously the barrel rotates w.r.t.

the turret about the z axis at a constant

10rad/s. What is the magnitude of the

velocity of a projectile at point B traveling

at 20m/s down the barrel at the instant

shown in m/s if the barrel is 3m long from

A to B (point A has zero velocity and

acceleration).
