While traveling in the far north, one of y our companions gets snow blindness, and you have to lead him along by the elbow. Looking back, you see your other companion, Sandy, fall and slide along the frictionless surface of the frozen river valley shown in Figure. If point Q is 4.5 m higher than point P, and your hapless companion fell at point P with a velocity v₀ down the slope, describe his motion to your snow-blind friend if 

(a) v₀ = 2 m/s

(b) v₀ = 5 m/s. 

(c) What is the minimum initial speed required for the fall to carry your partner past point Q?
