a truck at rest does not require any attention when parked along a roadside. But a moving truck, even at speeds as low as 5m s ,may kill a person standing in its path. A small mass , such as a bullet may kill a person when fired from a gun. Why

Dear Student,

During the motion of the body if momentum changes then a force will be applied on the body due to which a moving truck,  and bullet may kill a person because in both the cases momentum changes during the hit and a force is applied on both the person and other object.

It is because trucks mass is enough to kill a person and an a bullet even with less mass but have sufficient velocity to enter anyone's body and if it enters in the body it will obviously kill the person
