That's unaccelerated motion,
and constant velocity.
Answer:
The velocity of the pin will be 6.26 m/s in the right direction.
Explanation:
Let's use the momentum conservation equation.

Initially, we have:

Where:
- m(b) is the ball mass
- v(ib) is the initial velocity of the ball
Now, the final momentum will be:

Where:
- m(p) is the pin mass
- v(fb) is the final velocity of the ball
- v(fp) is the final velocity of the pin
Then, using the equation of the conservation we have:




Therefore the velocity of the pin will be 6.26 m/s in the right direction.
