Apuck moves 2.35 m/s in a -22° direction. a hockey stick pushes it for 0.215 s, changing its velocity to 6.42 m/s in a 50.0° direction. what was the direction of the acceleration?

The puck starts with velocity vector

Its velocity at time is

Over the 0.215 s interval, the velocity changes to

Then the acceleration must have been

which has a direction of about .

this a false

explanation:

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
