Explanation: Let : vr = x + y , x = 5 m , y = V y t = (6 m / s) t , and t = 4 s . Basic Concepts: v L = vr vp Solution: vV = vr t = V y = (6 m / s) . v L = vr vp = m vr vV = m vr vr t = m ( vx + vy ) vV = m x V y k = (2 kg) (5 m) (6 m / s) k = 60 kg m 2 / s k , and is constant as a Function oF time since = 0 ....
