A12-kg hammer strikes a nail at a velocity of 8.5 m/s and comes to rest in a time interval of 8.0 ms. (a) what is the impulse given to the nail? (write the unit for impulse as a kg. m/s or as n. s)

The impulse is 102 kg m/s.

Explanation:

Given that,

Mass of hammer = 12 kg

Velocity = 8.5 m/s

Time = 8.0 ms

Impulse :

Impulse is the change in momentum of the object.

We need to calculate the impulse

Using formula of impulse

Where, m = mass of the object

v = final velocity

u = initial velocity

Put the value into the formula

Hence, The impulse is 102 kg m/s.
