Problem: The collision between a hammer and a nail can be considered to be approximately elastic. Calculate the kinetic energy acquired by a 13-g nail when it is struck by a 560-g hammer moving with an initial speed of 4.6m/s .

FREE Expert Solution

The formula for kinetic energy is given as:

K=12mv2

For head-on collisions:

v1f=(m1-m2)(m1+m2)v10

and 

v2f=2m1(m1+m2)v10
