Question

A ball is dropped from a height of 100 m. It is
embedded into sand 1 m and stops, then
(1) Momenturn of the ball and the earth (system)
remains conserved
(2) Only kinetic energy of the ball and the earth
(system) remains conserved
(3) Both momentum and kinetic energy of the ball
and the earth (system) are conserved
(4) Neither momentum nor kinetic energy of the
ball and the earth (system) is conserved
​

Answer 1

Answer:

1

Explanation:

as a system momentum is conserved.
