The skier starts fom rest at A and travels down the ramp. If friction and air resistance can be neglected, determine his speed when he reaches B. Also, compute the distance s to where he strikes the ground at C, if he makes the jump traveling horizontally at B. Neglect the skier's size. He has a mass of 70 kg.
