A projectile is projected from the origin with a velocity of 30
1 answer:
For this we will use kinematic equations.
We need the time of flight to compute the range.
With the given information, the most useful formula is:
Δy=v0yt−g2t2
Because our equation is taking only vertical motion into account,
v0y=30sin(45)
Because we are looking for the range of the object,
Δy=0
This leaves us with only one unknown: t
0=30sin(45)t−g2t2
g2t2=30sin(45)t
g2t=30sin(45)
t=60gsin(45)
For horizontal distance, the formula we need is:
Δx=v0xt
Because we are taking into account the horizontal range,
v0x=30cos(45)
In substituting our derived values into the equation we can see that:
Δx=30cos(45)∗60gsin(45)
Range=30cos(45)∗60gsin(45)

The persuasive techniques that were used in the given poster are; Option A; glittering generalities about the viewer. and Option C; fear over a possible outcome
The poster is missing and so i have attached it.
The painting in the attached image was one created by Norman Rockwell released by the United Kingdom's Royal Navy during World War II.
The intentions and message the poster is trying to communicate is very direct because it tells us that if the workers waste time, the production rate of ships and destroyers will definitely decrease and as such the war will continue and it will take a far longer time to win the war.
The persuasive technique used in this poster is that it shows the glittering generalities about the viewer and from the images fear over a possible outcome.
