Question

If an object accelerates from rest, with a constant acceleration of 6.4 m/s2, what will

its velocity be after 18s?

Answer 1

120 m/s

Step-by-step explanation:

Acceleration = 6.4 m/s²

Initial velocity = 0 m/s

Time = 18 s

v = at + v₀

v = (6.4)(18) + 0

v = 115.2

Rounded to two significant figures, the final velocity is 120 m/s.
