dip with catch
Step By Step
start in the extension
0.12m from the start of the extension
2.52m from the ground
0.12m from the prep position
2.4m from the ground
1.44m from the dip position
0.96m from the ground
The force applied onto the flyer during an extension
speed of the flyer going into the extension
velocity of the flyer during the cradle
What would happen if we changed any of the variables during the extension?
change the weight of the flyer:
depending on if she is heavier or lighter, the speed of the extension could be slower or faster.
Change the force that the bases apply:
if the bases increase their force that they apply to the flyer, the speed of the extension will get faster, but if the bases decrease the force that they apply to the flyer, the speed of the extension will slow down
what would happen if you changed a variable during the cradle?
changing the weight of the flyer would affect the speed at which the flyer would fall during the cradle
changing the force at which the bases threw the flyer would also affect the rate at which the flyer would fall. if the bases throw the flyer with less force then the flyer wouldn't go as high and wouldn't be able to fall as fast as if the bases would have thrown her with a lot more force.
