Blood in the aorta accelerates from rest to 0.4 m/s over a distance of 2 cm. What is the average acceleration? A)4 m/s² B)4 m²/s² C)8 m²/s D)8 m/s²

Question

Quizplus · Accepted Answer

The average acceleration can be calculated using the formula $ a = \frac{v^2 - u^2}{2s} $, where $ v = 0.4 \, \text{m/s} $, $ u = 0 \, \text{m/s} $, and $ s = 0.02 \, \text{m} $. Substituting these values gives $ a = \frac{(0.4)^2 - 0^2}{2 \times 0.02} = 8 \, \text{m/s}^2 $.
