1. An Olympic athlete throws a shot put with an initial velocity that makes an angle of 30.0 degrees with the horizontal. The shot put leaves the athlete's fully extended arm at a height of 1.8 m above the ground and lands a horizontal distance of 4.8 m away from the release point. Determine the maximum height (above the ground) reached by the shot put. 2. An airplane attempts to drop a bomb on a target. When the bomb is released, the plane is flying upward at an angle of 30 degrees above the horizontal at a speed of 200 m/s. At the point of release, the plane's altitude is 2.0 km. The bomb hits the target.
a) Determine how much time it takes for the bomb to hit the target after it is released.
b) Determine the magnitude and direction of the vertical component of the bomb's velocity at the point of release.
c) At the point of release, what angle below the horizontal does the pilot have to look in order to see the target?
d) Determine the magnitude and direction of the horizontal component of the bomb's velocity at the point when the bomb contacts the target.

I just did this question did i???

Explanation:

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).
