an object moving North with an initial velocity of 14 m s accelerates 5 Ms ^2 for 20 seconds what is the final velocity of the object

Respuesta :

SINAZEUS
the final velocity is 114m/s
[tex]5 = \frac{x - 14}{20} \\ x = \frac{20 \times 5}{1} + 14 = 100 + 14 \\ 114[/tex]

Answer:

The final velocity of the object is 114 m/s.

Explanation:

It is given that,

Initial velocity of the object, u = 14 m/s

Acceleration of object, [tex]a=5\ m/s^2[/tex]

Time taken, t = 20 s

Let v is the final velocity of the object. It can be calculated using first equation of motion as :

[tex]v=u+at[/tex]

[tex]v=14\ m/s+5\ m/s^2\times 20\ s[/tex]

v = 114 m/s

So, the final velocity of the object is 114 m/s. Hence, this is the required solution.
