Chapt. 2One-Dimensional Kinematics17002 qmult 00250 1 1 5 easy memory: timeless equation21. The constant-acceleration kinematic equation without the time variable (which can be calledthe timeless equation for mnemonic reasons) is:a)v2=v20−2aΔx.b)v=v0+ 2aΔx.c)v2=v20+ 2a/Δx.d)v2=v20+aΔxe)v2=v20+ 2aΔx.002 qmult 00310 1 3 3 easy math: d=vt calculationExtra keywords:physci22.
