A fireworks show is choreographed to have two shells cross paths at a height of 157 feet and explode at an apex of 196 feet under normal weather conditions. If the shells have a launch angle 0 = 60° above the horizontal, determine the common launch speed vo fo the shells, the separation distance d between the launch points A and B, and the time t from launch at which the shells explode.

A batter hits the baseball A with an initial velocity of v0 = 114 ft/sec directly toward fielder B at an angle of 22° to the horizontal; the initial position of the ball is 2.5 ft above ground level. Fielder B requires 0.42 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. The catch position is the field location at which the ball altitude is 8.5 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made.
Q1) The shooter in position A throws a ball when the receiver is at the position B, as shown in Figure (1). The receiver's velocity is constant at 5 m/sec, and he catches passes when the ball is 2 m above the ground. If the shooter desires the receiver to catch the ball at 55 m away from point A, determine the required initial speed vo and angle 0, to achieve that. 2.5 m U= 5m/sec 30 m Finure t

A batter hits the baseball A with an initial velocity of v0 = 108 ft/sec directly toward fielder B at an angle of 23° to the horizontal; the initial position of the ball is 2.9 ft above ground level. Fielder B requires 0.47 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. The catch position is the field location at which the ball altitude is 6.3 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made.
