Question

An object moves from the position +34 m to the

position ­15 m in 15 s. What is its total
displacement? What is its average velocity?

Answer 1

That’s the answer above ^***

Answer 2

Answer: Displacement: -19m; Velocity: -1.27m/s

-

Δd = d(final) – d(initial)

Δd = 15m – 39m

Δd = -19m

-

v = Δd/t

v = -19m/15s

v = -1.27 m/s
