Person walks up the step and most of his body weight is distributed on back leg and little weight placed on front leg. The normal vector for the back leg is greater than the front leg.
Does this mean that the friction vector for the back leg will be greater than the front leg’s friction vector?
The sum of two normal vectors is greater than the weight vector.
Is the person speeding up, slowing down, or moving in constant speed in horizontal direction?
What about vertical? Is person slowing down, speeding up or moving at a constant speed?
