The magnitude and direction of the momentum of the bale the moment before the plane strikes the ground.
Answer to Problem 57A
The magnitude of the momentum of the bale the moment before the plane strikes the ground is
The direction of the momentum of the bale the moment before the plane strikes the ground is
Explanation of Solution
Given:
The initial velocity of the plane is
The altitude is
The weight of the bale of hay is
Formula used:
The expression for the velocity of the bale before striking the ground
Here,
The expression for the magnitude of the momentum is,
Here,
The expression for the direction of the momentum is,
Calculation:
The velocity of the bale before striking the ground as follows:
The magnitude of the momentum is,
The direction of the momentum as follows:
Conclusion:
Therefore, the magnitude of the momentum of the bale the moment before the plane strikes the ground is
