A bowling ball with a mass of 7kg collision with a pin in rest with a mass of 2kg, after the collision the pin acquired a velocity of 6m/s and the ball continues with a velocity of 4m/s, both to the front. What was the initial velocity of the ball?

I forget to write at the end to ignore the friction

I do have the answer just need verify is my answer is correct (Vi=3.6m/s)

The ballistic pendulum is a block with the mass 2.50kg suspended on a cable, the projectile has a mass of 0.010kg and is shouted with the initial velocity, after the collision the pendulum reach the height of h=0.65 m/s. Determine the initial velocity of the projectile.
