A boat takes off from the dock at 2.5m/s and speeds up at 4.2m/s2 for 6.0 seconds how far has the boat traveled
suter [353]

Answer:

The answer is "91 m"

Explanation:

v_0 = 2.5 \ \frac{m}{s}\\\\a = 4.2\ \frac{m}{s^2}\\\\t = 6.0\ s\\\\\Delta x=?

Using formula:

\Delta x = v_0 t +\frac{1}{2} at^2\\\\

      = 2.5 \times 6.0  +\frac{1}{2}  \times  4.2 \times 6.0^2\\\\= 90.6\  m \approx 91\ m
