Which formula cannot 'translate' to vectors

s = ut + ½at²

v = u + at

s = ½(u+v)t

v² = u² +2as

What's the new formula?

r₀ = r + vt

r = r₀ + at

r = r₀ + vt

r₀ = r + at

Particles will collide if ...

they have travelled the same distance in the same time

they have the same velocity at the same time

it is meant to be

they have the same displacement from an origin at the same time

What's NOT necessarily true at maximum speed

v = 0

da/dt = 0

a = 0

dv/dt = 0

v = 2^t

a = 2^tln2

x = 2^tlnt

a = 2^tlnt+C

x = 2^tln2+C
