## Physics: Principles with Applications (7th Edition)

Their final velocity is zero, and their starting velocity is 26.4 m/s. Find the acceleration from equation 2–11c. $$a=\frac{0-(26.4 m/s)^2}{(2)(0.8 m)}= -436 \frac{m}{s^{2}}$$ The magnitude of the acceleration is $\approx 440 \frac{m}{s^{2}} \approx 44g$.
