Assume that when you stretch your torso vertically as much as you can, your center of mass is 1.0 m above the floor. The maximum force you can exert on the floor in pushing off is 2.3 times the gravitational force Earth exerts on you
How low do you have to crouch in order to jump straight up and have your center of mass be 2.0 m above the floor? Determine the lowest height of your center of mass above the floor in the jump.?
Is this crouch practical?
