Apuck 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.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
