SUMMARY
The momentum of a falling bale of hay just before impact can be calculated using the formula momentum = mass * velocity. Given that the bale weighs 161 N, the mass can be determined by rearranging the weight formula to mass = weight/gravity, where gravity is approximately 9.81 m/s². This results in a mass of approximately 16.4 kg. The velocity of the bale just before impact, considering it falls from an altitude of 52.8 m, can be calculated using kinematic equations, yielding a final velocity of approximately 36.0 m/s. Thus, the momentum just before impact is approximately 590.4 kg·m/s directed eastward.
