  1. Acceleration Equations (continued)

  2. Base equation for acceleration Equation (1) Rearranged to solve for final velocity Rearranged to solve for time

  3. What is different about this equation compared to the previous one? Has displacement Missing final velocity Equation (2) Can also be written like this: Be able to solve for any variable in the equation!

  4. What is different about this equation compared to the first one? Has displacement Missing time interval Equation (3) Can also be written like this: Be able to solve for any variable in the equation!

  5. Another way to express the average velocity. Equation (4)

  6. Examples 1. A plane starting a rest at one end of a runway undergoes a constant acceleration of 4.80m/s2 for 15.0s before takeoff. What is its speed at takeoff? How long must the runway be for the plane to be able to take off? vi = 0m/s a = 4.80m/s2 t = 15.0s vf= ? d =? a Solve for one unknown at a time

  7. Examples 2. A baby sitter pushing a stroller starts from rest and accelerates at a rate of 0.500m/s2. What is the velocity of the stroller after it has traveled 4.75m? vi = 0m/s a = 0.500m/s2 vf = ? d =4.75m a
