2-D Kinematics So for constant acceleration we get a= const 0 +a t +vt+1 a t2 (where a, V, Vo, r, ro, are all vectors) Physics 121: Lecture 6, Pg 8Physics 121: Lecture 6, Pg 8 2-D Kinematics So for constant acceleration we get: a = const v = v0 + a t r = r0 + v0 t + 1 /2 a t 2 (where a, v, v0 , r, r0 , are all vectors)
