A car starting from rest ends up going 45 m/s in 12 sec. How far did they travel during this time?

What is 45 m/s?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car starting from rest ends up going 45 m/s in 12 sec. How far did they travel during this time?

v_f = 45 m/s

What is 12 sec?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car starting from rest ends up going 45 m/s in 12 sec. How far did they travel during this time?

v_f = 45 m/s
Δt = 12 sec

What is "starting from rest"?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car starting from rest ends up going 45 m/s in 12 sec. How far did they travel during this time?

v_f = 45 m/s
Δt = 12 sec
v_i = 0 m/s

What are you looking for?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car starting from rest ends up going 45 m/s in 12 sec. How far did they travel during this time?

v_f = 45 m/s
Δt = 12 sec
v_i = 0 m/s
Δx = ___

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
