A baseball is pitched,reaching the batter with a speed of 37 m/s and is hit such that it returns on the same line at 48 m/s.If the ball was in contact with the bat for 0.22 seconds,what was the average acceleration experienced by the ball during the time of contact? A) 220 m/s² B) 41 m/s² C) 390 m/s² D) 170 m/s²

The average acceleration is calculated using the formula: a = (v_f - v_i) / t. Here, v_f = 48 m/s (final velocity), v_i = -37 m/s (initial velocity, negative because it's in the opposite direction), and t = 0.22 s. So, a = (48 - (-37)) / 0.22 = 390 m/s².
