From a crouched position an excellent human jumper launches herself upwards. the jumpers full height is 168 cm, but in the crouched position her height is half of that value. the jumper accelerates from the crouched position until she reaches her full height. her motion then carries her upward until her center of mass is 90 cm above its position when she is standing. at what velocity must the jumper leave the ground to reach this height? what constant acceleration must be maintained to reach this initial velocity? assuming a constant acceleration, how long in seconds does it take to accelerate from rest to this initial velocity?
