<span> The
Grand Canyon is made up of sedimentary rock; over time, sediments formed into
layers. The layers on the bottom are the oldest, and the layers on the top are
the youngest and newest.
Try and paraphrase though</span>
A) The ball on the small ball is far smaller than the force on the basketball.
B) The total momentum before and after the collision remains constant.
C) We know momentum is conserved so we do:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.1 x 5 + 0.6 x 0 = 0.1 x -4 + 0.6 x v₂
v₂ = 1.5 m/s
