Question

A motorboat starting from rest travels in a straight line on alake. (a). If the boat achieves a speed of 14 m/s in 12 s. What isthe boats average acceleration?-----m/s^2 (b)Then, in 5.0 more seconds, the boat's speed is 20 m/s. Whatis the boats average acceleration for the total time?-----m/s^2 A motorboat starting from rest travels in a straight line on alake. (a). If the boat achieves a speed of 14 m/s in 12 s. What isthe boats average acceleration?-----m/s^2 (b)Then, in 5.0 more seconds, the boat's speed is 20 m/s. Whatis the boats average acceleration for the total time?-----m/s^2

Explanation / Answer

For this problem, you need to use this equation: vf = vo + at For part (a), acceleration will be 1.166 m/s2 For part (b), acceleration will be 1.176 m/s2
