Find final velocities in the reference frame to the ground.

Click For Summary
SUMMARY

The discussion focuses on calculating final velocities in the ground reference frame after a collision involving a bat and a ball. The initial velocities are given as 37 m/s for the ball and -35 m/s for the bat. The final velocities calculated in the bat's reference frame are -46.5 m/s for the ball and 25.4 m/s for the bat. The conversion from the bat's frame to the ground frame involves understanding the relative velocities and applying the correct formulas, specifically V + v, where V is the bat's velocity relative to the ground and v is the ball's velocity relative to the bat.

The velocity wrt the ground is already what we need.
