Question

state the law of conservation of momentum why is a person Hit hard and When he falls on sand from the same height

Answer 1

A person hit harder when he falls on a concrete floor than when he falls on a heap of sand from the same height because On a hard surface he is brought to rest in a very short time, so greater force is called into play, whereas, on a heap of sand, he is brought to rest in a longer time, so lesser force is called into play (or explanation in terms of momentum)

 

Answer 2

now I am going t
According to the law of conservation of momentum...THE TOTAL INITIAL MOMENTA OF A BODY IS EQUAL TO THE TOTAL FINAL MOMENTA OF THE BODY...SO weekend so why was
IF A PERSON FALLS hard concrete ground then Hit hard because force is directly proportional to time but directly proportional to the linear change in momentum so when a person falls in the ground the linear change of momentum is suddenly suddenly comes to zero 20 But When he falls in from same height inside the the time is increased and as we know force is indirectly proportional to time so there is less force acting on the body and he did not get hit and also get saved from injury hope you like the answer
