Suggest a suitable physical situation for following graphs.
The given $a-t$ graph reveals that initially the body is moving with a certain uniform velocity. Its acceleration increases for a short interval of time, which again drops to zero. This indicates that the body again starts moving with the same constant velocity. As imilar physical situation arises when a hammer moving with a uniform velocity strikes a nail.
