Textbook Question
Chapter 14.5, Problem 86P
The skier starts from rest at A and travels down the ramp. If friction and air resistance can be neglected, determine his speed vB 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.

If the 40 kg skier passes point A with a speed of 2 m/s, determine his speed when he reaches point B. Also find the normal force exerted on him by the slope at this point. Neglect friction.
The baseball player A hits the baseball at VA = 40 ft/s and θA = 60° from the horizontal. When the ball is directly overhead of player B he begins to run under it. Determine the constant speed at which B must run and the distance d in order to make the catch at the same elevation at which the ball was hit.
It takes 33 s for the 48-Mg tugboat to increase its speed uniformly to 25 km/h, starting from rest. The propeller provides the propulsion force F which gives the tugboat forward motion, whereas the barge moves freely. The barge has a mass of 80 Mg.
