(P12.232)-The football player at A throws the ball in the y–z plane at a speed VA = 50 ft/s and an angle UA = 60° with the horizontal. At the instant the ball is thrown, the player is at B and is running with constant speed along the line BC in order to catch it. Determine this speed, VB, so that he makes the catch at the same elevation from which the ball was thrown. J-Loaded Solutions
(P12.233)-The football player at A throws the ball in the y–z plane with a speed Va = 50 ft>s and an angle uA = 60° with the horizontal. At the instant the ball is thrown, the player is at B and is running at a constant speed of Vb = 23 ft/s along the line BC. Determine if he can reach point C, which has the same elevation as A, before the ball gets there J-Loaded Solutions
(P12.235)-At the instant shown, car A travels along the straight portion of the road with a speed of 25 m/s. At this same instant car B travels along the circular portion of the road with a speed of 15 m/s. Determine the velocity of car B relative to car A. J-Loaded Solutions
