Consider the motion of a projectile P of mass mP = 18.5 kg, which is shot with an initial speed υP = 1675 m/s as shown in the figure. Ignore aerodynamic drag forces.

Figure P5.81

Knowing that the helicopter E happens to have the same horizontal coordinate of the projectile at the instant the projectile leaves the gun and that it moves at a constant speed υE = 15 m/s as shown, and treating E as a moving moment center, verify the angular impulse-momentum principle as given in Eq. (5.64).
