v_i = 0.5 m/s

What is 1.2 m/s²?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
In 3 m a person running 0.5 m/s accelerates 1.2 m/s². How fast were they going afterward?

Δx = 3 m
v_i = 0.5 m/s
a = 1.2 m/s²

What are you looking for?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
In 3 m a person running 0.5 m/s accelerates 1.2 m/s². How fast were they going afterward?

Δx = 3 m
v_i = 0.5 m/s
a = 1.2 m/s²
v_f = ?

Which equation can you use?
1. v_f = v_i + aΔt
2. Δx = v_iΔt + (½)a(Δt)²
3. v_{_f}² = v_i² + 2aΔx
4. Δx = (½)(v_i + v_f)Δt
