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? 39 m/s 90 m/s 114 m/s 414 m/s

Final velocity of the object(v) = 114 m/s

Explanation:

Given:

Initial velocity (u) = 14 m/s

Accelerates (a) = 5 m/s²

Time taken = 20 seconds

Find:

Final velocity of the object(v) = ?

Computation:

According to 1st law of motion.

⇒ v = u +at

⇒ v = 14 + (5)(20)

⇒ v = 14 + 100

⇒ v = 114 m/s

Final velocity of the object(v) = 114 m/s
