Plane Curvilinear Motion - n-t Coordinates - Example 3.3-3

 

Consider the ski jumper shown in the figure. Neglect surface friction and air resistance. Determine the acceleration direction of the skier at position A, B and C. Use the arrow diagram to describe the direction.

 

 

What is the acceleration direction of the skier at position A?

 

1     2     3     4     5     6     7     8    

 

 

 

What is the acceleration direction of the skier at position B?

 

1     2     3     4     5     6     7     8    

 

 

 

What is the acceleration direction of the skier at position C?

 

1     2     3     4     5     6     7     8
