Activity 17A - Seminar Problems & Solutions

Activity 27.10

An object in free fall is accelerating at 9.8 m/s^2 down all the time.

So an object tossed or hit upwards is slowing down at a rate of 9.8 m/s all the way up, and speeding up at a rate of 9.8 m/s all the way down.
  • At its peak,  an  object in free-fall has a vertical velocity of zero (for an instant). 
  • The motion of an free falling object tossed up is perfectly symetrical.  It takes the same amount of time to go up, as it takes to go down,  and it's speed going up is the same as it's speed going down at every vertical height.

Complete these two seminar problems on Free Falling bodies. (You do not need to do section f: "using logger pro"  on the second Romeo & Juliet problem) When done check your answers here.
