Solving Kinematic Equations 1

A car is going 3 m/s, then it speeds up for 4 seconds. If it has an acceleration of 5 m/s² and travels 46 meters, find its final velocity.

What is 3 m/s?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car is going 3 m/s, then it speeds up for 4 seconds. If it has an acceleration of 5 m/s² and travels 46 meters, find its final velocity.

v_i = 3 m/s

What is 4 sec?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car is going 3 m/s, then it speeds up for 4 seconds. If it has an acceleration of 5 m/s² and travels 46 meters, find its final velocity.

v_i = 3 m/s
Δt = 4 sec

What is 5 m/s²?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car is going 3 m/s, then it speeds up for 4 seconds. If it has an acceleration of 5 m/s², find its final velocity.

v_i = 3 m/s
Δt = 4 sec
a = 5 m/s²

What are you looking for?
1. Δt
2. Δx
3. a
4. v_i
5. v_f
A car is going 3 m/s, then it speeds up for 4 seconds. If it has an acceleration of 5 m/s², find its final velocity.

v_i = 3 m/s
Δt = 4 sec
a = 5 m/s²
v_f = ? (your unknown)

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
