Warm Up- Basic vector question in 3D

You stand in BLOC at the position of 15m east, 20 m north, and on the stairs of the first floor, so 2 m high. You proceed to travel north 7 m before turning to continue up the stairs and traveling 11 m south. You then take a westward turn and proceed for 3 m. Your traveled roughly 13 ft upwards. What is your final position?

Main activity.- Popular Question

A sniper is firing from 3/4 the way up a hill that is 60 meters high at a target 1700 yards away. The bullet is known to leave the muzzle of the rifle at 2400 feet per second. Assume the target is 6 feet off the surface of the ground. How far above the target should the sniper aim?

​

Tips for this question: Make sure you understand which component of motion you have to perform calculations with. This is critical to solving this question accurately.

Cool Down- Reviewing and Questions

-Any questions? Now is a great time to ask. Make sure you walk out of here with no new questions.

Brief Concept Review

-One ball is thrown from a building with horizontal velocity, another is dropped, which one lands first?

-You throw a ball at 45 degrees, with initial velocity 3 m/s, what is horizontal acceleration?

-You run back and forth for 1 hour covering a total of 700 m. What is your velocity?
