An animal-rescue plane flying due east at 49 m/s drops a bale of hay from an altitude of 66 m . the acceleration due to gravity is 9.81 m/s 2 . if the bale of hay weighs 160 n , what is the momentum of the bale the moment it strikes the ground? answer in units of kg m/s. at what angle of inclination will the bale strike?

Explanation:

The final velocity of the bale have vertical and horizontal components. So, we have:

According to conservation of energy:

Since the plane is flying due east, we have . Replacing in (1):

Now, we calculate the momentum of the bale:

From pythagoras theorem we know that:

answer is c

explanation:

real, smaller and upside-down.   so the answer should be b.
