Question

the averge force neccessary to stop a hammer with momentum p NS in 0.5..​

Answer 1

Answer:

= 2pN

Explanation:

F= change in momentum/ time

= p- 0 = p

= t = 0.5

=p/ 0.5

= 1/ 0.5

hope its help u.............

thank u.....................TC❤

Answer 2

Force = change in momentum / time

here, initial momentum = p

if hammer comes to rest, final momentum = 0

change in momentum = p - 0 = p

time = 0.5s

Average force = p/0.5 = 2p N

Average force is 2p Newton
