Question

An object moving north with an initial velocity of 14 m/s accelerates 5 m/s2 for 20 seconds. What is the final velocity of the object?

Answer 1

Answer:

Final velocity of the object is 114 m / s.

Explanation:

Here,

Initial Velocity = 14 m / s

Acceleration = 5 m / s^2

Time taken = 20 seconds

We know,

Acceleration = ( Final velocity - Initial velocity ) / time taken

Therefore,

= > 5 m / s^2 = ( Final velocity - 14 m / s ) / 20 s

= > 5 m / s^2 x 20 s = Final velocity - 14 m / s

= > 100 m / s = Final velocity - 14 m / s

= > 100 m / s + 14 m / s = Final velocity

= > 114 m / s = Final velocity

Hence, final velocity of the object is 114 m / s.
