Question 11

The following graph shows the time dependence of the x-coordinate of a movement along the x-axis. The curve corresponds to a parabola.

Please draw the curves for the time dependence of the corresponding velocity and acceleration (only qualitatively).

v=f(t) straight line

Average: = 30%

v=f(t) neg. slope

Average: = 15%

v=0 for x = max

Average: = 15%

a=f(t) hor. line

Average: = 19%

a=f(t) negative

Average: = 9%

Comment:

These results are so poor that not much is to say. May be this topic - drawing such diagrams when treating the vertical throw - was not covered in classroom. This would be a shame for the teacher. And if it was treated, it was not done in an efficient way.
