Final Velocity after Any Displacement
The Last Equation…For now
The Last Equation
• If we take the equations that we’ve looked at so far, and do some mathematical hand waving…
• We get:

Example
• A person pushing a stroller starts from rest, uniformly accelerating at a rate of 0.500 m/s2. What is the velocity of the stroller after it has traveled 4.75m?
