(a) Show that the speed v of the food pack is v boy , where x is the distance he has

walked away from the vertical rope. (b) Show that the acceleration a of the food pack is

(c) What values do the acceleration and velocity have shortly after he leaves the point under the pack

(x _ 0)? (d) What values do the pack’s velocity and acceleration approach as the distance x continues to increase?
