a puck moves 2.35 m/s in a - 22.0 direction. A hockey stick pushes it for 0.125s, changing its velocity to 6.42m/s in a 50.0 direction. what was the magnitude of the accerlation

48.9 m/s²

Explanation:

The acceleration is given by ...

a = (change in velocity) / (time)

= ((final velocity) - (initial velocity)) / time

= ((6.42∠50° - 2.35∠-22°) m/s) / (0.125 s)

≈ (6.12∠71° m/s) / (0.125 s)

≈ 48.9∠71° m/s²

The magnitude of the average acceleration was 48.9 m/s².
