Formulas
r(t) = x(t)i + y(t)j
x(t) = at + b
y(t) = ct^2 + d
Average velocity: v_avg = (r(t2) - r(t1)) / (t2 - t1)
Instantaneous velocity: v(t) = dr/dt = dx/dt i + dy/dt j
Speed = sqrt(vx^2 + vy^2)
Theorems
Derivative of position function gives velocity
Average velocity formula
Pythagoras theorem for calculating speed from velocity components
Suitable Grade Level
