in this question we have given
mass of cart=5kg
change in speed,
we have to find, impulse, i=?
impulse of a body is equla to its change in momentum.
impulse of cart is equal to its change in momentum:
, and m in eq(1)
therefore, the impulse of the cart,
momentum can be explained by a game of pool. a ball which is hit by the rod moves with certain mass and certain velocity. that ball hits another one and makes it move, also. so by giving it acceleration, a transfer of momentum is made.
