(a)
The impulse given to the nail.
(a)
Answer to Problem 16P
Explanation of Solution
Given:
Mass of the hammer is
The velocity with which the hammer strikes the nail is
Final velocity of the hammer is
Formula used:
The impulse
Where,
Calculation:
Substituting the numerical values in equation
Negative sign indicates that the impulse acting on the nail is in the direction opposite to the direction of motion of the hammer.
Conclusion:
The impulse given to the nail is
(b)
The average force acting on the nail.
