An animal-rescue plane flying due east at

30 m/s drops a bale of hay from an altitude of
65 m .
The acceleration due to gravity is
9.81 m/s^2
If the bale of hay weighs 182 N , what is the
momentum of the bale the moment it strikes
the ground?
What angle of inclination will the bale strike?

1 answer

how long does it take to hit the ground?
4.9t^2 = 65
t = 3.64s
horizontal speed is constant: 30
vertical speed is v = gt = 9.81*3.64 = 35.73
momentum is |p| = m|v| = 182/9.81 √(30^2 + 35.73^2)
it hits at an angle θ where tanθ = 35.73/30
