Lacrosse stick rotating \(90^\circ\) from horizontal (A) to vertical (B), releasing the ball at \(10\,\text{m/s}\).
Lacrosse stick rotating \(90^\circ\) from horizontal (A) to vertical (B), releasing the ball at \(10\,\text{m/s}\).
In lacrosse, a typical throw is made by rotating the stick through an angle of roughly \(90^\circ\), then releasing the ball when the stick is vertical, as shown above. If the \(1\,\text{meter}\) long stick is at rest when horizontal and the ball leaves the stick with a velocity of \(10\,\text{m/s}\), what angular acceleration must the stick experience?
