Amotorboat is moving at 4.0 m/s when it begins to accelerate at 1.0 m/s^2. to the nearest tenth of a second, how long does it take for the boat to reach a speed of 17.0 m/s? show work.

Time taken by motorboat to reach equals 13 seconds.

Explanation:

From the first equation of kinematics we have

where,

'v' is the final speed of the accelerating object

'u' is the initial speed of the object

'a' is the accleration of the object

't' is the time for which the object accelerates

Applying the given values in the equation above we get

frequency or wavelenth of em radiation in a vacuum
