Answer:
Explanation:
Given
Initial Moment of Inertia
initial Spin
Final Moment Moment of Inertia
Conserving Angular momentum
Differentiate the components of position to get the corresponding components of velocity :
At <em>t</em> = 5.0 s, the particle has velocity
The speed at this time is the magnitude of the velocity :
The direction of motion at this time is the angle that the velocity vector makes with the positive <em>x</em>-axis, such that
