Question

please give me answer for this☝️​

Answer 1

Answer:

remaining balls also move atlast it touches last ball

rolling doesn't occur if we bring both marbles

law of conservation of momentum

in the absence of external force the toatal momentum is constant

Answer 2

Answer:

simple here,

if one ball is taken to end and left after collision ,the last ball on the other side will start moving to its extreme.

if two balls ,are brought and left, after colliding two balls on others side will go extreme and come and collide again....the first two balls and last two balls and so on.

this is what happens in newtons cradle.

hope this is very clear enough.

this is law of conservation of linear momentum.
