The x-acceleration a, is constant between times t, and t2. Let x1 and vx1 be the x-position and x-velocity at
time t1, and x2 and v2x be the same at time t2. Let At be t2 - t1. Choose all expressions which must be true if
the acceleration is constant.
x2 = *1 + V1zAt + ;a (At)²
V2» = Vla + az (x2 – x1)
v = v + 2a, (x2 – 21)
V2» = Vlz + a (At)²
V2x = V1x + aAt
vie + 2azAt
