Answer:
Approximately
to the right.
Step-by-step explanation:
The velocity of the
block after the collision can be found using the conservation of momentum.
Before the collision:
- Velocity of the
block is
. - Velocity of the
block is
(negative since this block is moving to the left.)
After the collision:
- Velocity of the
block becomes
. - Velocity of the
block,
, needs to be found.
The momentum of an object is the product of its mass and velocity.
By the conservation of momentum:
.
Rearrange and solve for
:
.
In other words, the
block would be moving to the right (since
is positive) at approximately
after the collision.
