[Physics of Biking]

wouldnt vectors be used for biking as well because it is moving in diffrent directions and it has magnitude for how long the biking goes for a certian time. its similar to Vi Vf d A T formate for finding time traveled while biking, or finding the mangitude of the acceleration of the bike.

[cheerleading]

how about using ascelleration of how fast the cheerleaders are going when they do moves like pushing someone in the air for a fantsy trick. wouldnt their ascelleration increase at first the as the cheerleader repells down to the ground the asceleration then dcreses.
