Question

Law of conservation of momentum
Suppose an object A has mass m, and its initial velocity is u,. An object B has mass m and
initial velocity u,
According to the formula for momentum, the initial momentum of A is m, u, and that of B
is mu,
Suppose these two objects collide. Let the force on A due to B be F. This force will cause
acceleration in A and its velocity will become v.
.. Momentum of A after collision = m, v,
According to Newton's third law of motion, A also exerts an equal force on B but in the
opposite direction. This will cause a change in the momentum of B. If its velocity after
collision is ve
The momentum of B after collision = m. v. If F, is the force that acts on object B,
F = -F
..ma = -ma.............: F= ma
(v.-u ) (v, -u)
(v-u)
: a =
m(v- u) = - m (v-u)
..mv - mu
m, v. + mu
.. (m. v, + m, v )= (mu+m, u,
t

..mx -U) e-mx​

Answer 1

Answer:

Explanation:One of the most powerful laws in physics is the law of momentum conservation. ... For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
