Tangential and Centripetal Acc. of a Trajectory
This is a starter sheet for those wanting to visualize the trajectory on their own. This app allows you to define the parametric equations to examine the relationship between the kinematic vectors that come from such a model. Walk the velocity and acceleration vectors around to determine the maximum centripetal acceleration and tangential acceleration. (N.B. the point where the max tangential acceleration may not be at the same point where the projectile is turning fastest.)
Remember to substitute your fitted equations for the x(t) and y(t) components of the trajectory.
