  a) A rock is held over the edge of a cliff and thrown upwards with an initial velocity of 5 m/s .  What is it’s displacement after 5 seconds (relative to where it was released from)? b) Use an example to describe the difference between the distance that an object travels and its displacement.

  A projectile is launched with an initial velocity of 38 m/s , if the projectile lands on a platform that is 8m above the height that it was launched from, solve for; a) the velocity of the projectile just before it hits the platform.   b) the displacement of the projectile if it sticks to the platform (stays exactly where it lands).
