(Eq. 2) 0 = voy2 + gE 2 (30 m) (I have chosen gE = - 9.8 m/s2) Now to combination. Notice that we have two equations and two unknowns (gm and voy). Solve Eq. 2 for voy and substitute that into Eq. 1, and you have your answer! gm = 1/6 * gE = 1.6 m/s2 Ch. 4: #23 . An exceptional standing jump would raise a person 0.80 m off the ground.
