Free fall with initial velocity


When we now put it all together for this case, we end up with

r(t) = r0 + v0t - gt2/2 = (
0
0
) + (
v0x
v0y
) t - (
0
g
) t2/2

= (
v0xt
v0yt - gt2/2
)

which in components can be written as follows

x(t) = v0xt     and     y(t) = v0y - gt2/2

Similarly, for the velocity we arrive at

vx(t) = v0x     and     vy(t) = v0y - gt

Next, Walter Lewin studies some charistics of free fall with initial velocity.
