Solutions
Q1: Sketch the path of this imaginary coin, including a definition of coordinates. Label the following points on your sketch.
Point 1 The coin has just left your hand moving upwards
Point 2 The coin is about 1/4 of the way up to the top of its path
Point 3 The coin is about 3/4 of the way up to the top of its path
Point 4 The coin is exactly at its maximum height of about 2.5m
Point 5 The coin is about 1/4 of the way down from the top of its path
Point 6 The coin is about 3/4 of the way down from the top of its path
Point 7 The coin is just above your hand and is about to be caught
Q2: Assume upwards displacement is positive. Indicate the following points on your sketches. (In some cases there may be none, or more than one correct point. When this is so, explain in words.)
Point A Maximum displacement of the coin
Point B Zero displacement of the coin
Point C Minimum displacement of the coin
Point D Maximum velocity of the coin
Point E Zero velocity of the coin
Point F Minimum velocity of the coin
Point G Maximum acceleration of the coin
Point H Zero acceleration of the coin
Point I Minimum acceleration of the coin
