Answer:

Explanation:
We are asked to find the final velocity of the boat.
We are given the initial velocity, acceleration, and time. Therefore, we will use the following kinematic equation.

The initial velocity is 2.7 meters per second. The acceleration is 0.15 meters per second squared. The time is 12 seconds.
= 2.7 m/s - a= 0.15 m/s²
- t= 12 s
Substitute the values into the formula.

Multiply the numbers in parentheses.




Add.

The final velocity of the boat is <u>4.5 meters per second in the positive direction.</u>
Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
This is because, different colored object absorbs differnt wavelenght of light making it appears with different color. There is a spectrum of white light in which red have the longest wavelength.
