Answer the following questions for projectile motion on level ground assuming negligible air resistance (the initial angle being neither 0° nor 90° ): (a) Is the acceleration ever zero? (b) Is the acceleration ever in the same direction as a component of velocity? (c) Is the acceleration ever opposite in direction to a component of velocity? 15. For a fixed initial speed, the range of a projectile is determined by the angle at which it is fired. For all but the maximum, there are two angles that give the same range. Considering factors that might affect the ability of an archer to hit a target, such as wind, explain why the smaller angle (closer to the horizontal) is preferable. When would it be necessary for the archer to use the larger angle? Why does the punter in a football game use the higher trajectory? 16. During a lecture demonstration, a professor places two coins on the edge of a table. She then flicks one of the coins horizontally off the table, simultaneously nudging the other over the edge. Describe the subsequent motion of the two coins, in particular discussing whether they hit the floor at the same time.

14. Answer the following questions for projectile motion on level ground assuming negligible air
resistance (the initial angle being neither 0° nor 90° ): (a) Is the acceleration ever zero? (b) Is
the acceleration ever in the same direction as a component of velocity? (c) Is the acceleration
ever opposite in direction to a component of velocity?
15. For a fixed initial speed, the range of a projectile is determined by the angle at which it is
fired. For all but the maximum, there are two angles that give the same range. Considering
factors that might affect the ability of an archer to hit a target, such as wind, explain why the
smaller angle (closer to the horizontal) is preferable. When would it be necessary for the archer
to use the larger angle? Why does the punter in a football game use the higher trajectory?
16. During a lecture demonstration, a professor places two coins on the edge of a table. She
then flicks one of the coins horizontally off the table, simultaneously nudging the other over the
edge. Describe the subsequent motion of the two coins, in particular discussing whether they hit
the floor at the same time.
