Suppose at time t= 0 the football is kicked with initial velocity components Vxo and Vyo. Solve the equations above to find Vx(t) and Vy(t). You can make use of the formulas we worked out in class.
"Equations above":
ax = -kvx
ay = -g-kvy
formula worked in class:
v(t) = (g/k)(1-e^-k(t-to)) + Voe^-k(t-to)
so...
Vx(t) = Vocosθe^-kt
Vy(t) = (9.8m/s^2/k)(1-e^-kt) + Vysinθe^-kt
Is this correct?
