Answer:
The impulse transferred to the nail is 0.01 kg*m/s.
Explanation:
The impulse (J) transferred to the nail can be found using the following equation:
Where:
: is the final momentum
: is the initial momentum
The initial momentum is given by:
Where 1 is for the hammer and 2 is for the nail.
Since the hammer is moving down (in the negative direction):
And because the nail is not moving:
Now, the final momentum can be found taking into account that the hammer remains in contact with the nail during and after the blow:
Since the hammer and the nail are moving in the negative direction:
=
= -9.7 m/s
Finally, the impulse is:
Therefore, the impulse transferred to the nail is 0.01 kg*m/s.
