A0.25 kg arrow is moving at 5 m/s and hits a 0.10 kg apple. the apple sticks to the arrow, and both move to the right together. what is their velocity?

The arrow-apple combo will move with a velocity 3.6 m/s to the right.

Explanation:

Use the law of conservation of momentum to solve this problem. In this case the law can be written as follows:

from which the desired velocity can be isolated:

The arrow-apple combo will move with a velocity 3.6 m/s to the right.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
