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.

Question

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.

In a basketball game, the point guard A intends to throw a pass to the shooting guard B, who is breaking toward the basket at a constant speed of 10 ft/sec. If the shooting guard is to catch the ball at a height of 6.6 ft at C while in full stride to execute a layup, determine the speed vo and launch angle with which the point guard should throw the ball.

An archer shoots an arrow at a 87.61 m distant target; the bull's-eye of the target is at same height as the release height of the arrow. At what angle (in degrees) must the arrow be released to hit the bull's-eye if its initial speed is 30.41 m/s?
A guy is standing on a relatively flat surface (h = 0 m). A pesky drone is flying overhead at a height of 120 m above the ground and with a velocity of 15 m/s. The guy gets annoyed and fires an arrow with an initial velocity of 100 m/s the instant the horizontal distance between him and the drone is 5 m. At what angle must he fire the arrow in order to hit the drone? Take the guy's height to be 1.8 m. Just to clarify, would shooting an arrow follow the same rules as a regular projectile motion problem? Thanks.
