A fireworks show is choreographed to have two shells cross paths at a height of 162 feet and explode at an apex of 208 feet under normal weather conditions. The shells have a launch angle = 58° above the horizontal. If a strong wind induces a constant rightward acceleration of 16 ft/sec² for the fireworks shells, determine the horizontal shift Ax of the crossing point of the shells.

A fireworks show is choreographed to have two shells cross paths at a height of 161 feet and explode at an apex of 206 feet under normal weather conditions. The shells have a launch angle 0 = 59° above the horizontal. If a strong wind induces a constant rightward acceleration of 16 ft/sec² for the fireworks shells, determine the horizontal shift Ax of the crossing point of the shells. 45' 161' Answer: Ax= Vo A/0 ft B
Diloyudin shot a nerf gun with an angle of depression of 35° on top of the 3.66 meter high structure as he was shooting Filosofo with it. If the nerf gun shoots the projectile at 3 m/s.

Situation 03. A yacht is approaching the dock at 45 cm/s. A landing equipment was left on the dock and needs to be thrown to the yacht just before it can dock. The equipment is thrown 15 m/s at 30° with the vertical from the top of a tower 8.75m above the ship deck. Compute the distance from the dock to the yacht should the yacht be at the instant the equipment is thrown.

PROBLEM NO. 1 A ball is launched eastward from the ground at 30kph at 45 degrees angle from the ground. A shooter will shoot the ball at the peak of its trajectory. The shooter is 50m away from the plane of the ball's trajectory. The launch point of the ball is 20m west from the plane of trajectory's nearest point to the shooter. The gun's muzzle is 1.2m from the ground and the exit velocity of the bullet is 2736kph. Determine the angle the gun should be shot and the time after the ball's launch should the gun's trigger be pulled. Neglect trigger to bullet exit time and air friction.
