How do you solve for the displacement of an object that rises and falls near Earth, given initial upward velocity, and time?

You try to kick a soccer ball in mid-air, but miss completely. Instead your shoe flies off your foot, goes through the air, and eventually hits your head. What is the displacement of your shoe if it leaves your foot at an initial speed of 8 m/s and stays in the air for 1.5 seconds?

Summary

  1. vi- initial velocity
  2. m- meters
  3. s- seconds
  4. t- time
  5. a- acceleration
  6. g- acceleration from gravity
  7. d- displacement

Notes

    1. vi- initial velocity
    2. m- meters, s- seconds
    3. a- acceleration
    4. t- time
    5. d- displacement
    1. Remember that gravity always points down towards the earth
    2. a- acceleration
    3. The sign of acceleration is negative because the downward direction is defined to be negative.
