Explanation:

Hey there!!

Here,

Initial velocity (u) = 6m/s.

Acceleration (a) = 1.7m/s^2.

Time (t) = 4.2s.

final velocity (v) = ?

We have,

[tex]a = \frac{v - u}{t} [/tex]

Putting their values,

[tex]1.7 = \frac{v - 6}{4.2} [/tex]

7.14 = v - 6

v = 7.14 + 6

Therefore, the final velocity is 13.14 m/s.

Hope it helps....
