A projectile is fired with muzzle speed 250 m/s and an angle of elevation 45° from a position 30 m above ground level. Where doe
qaws [65]

The projectile's horizontal and vertical positions at time t are given by

x=\left(250\dfrac{\rm m}{\rm s}\right)\cos45^\circ\,t

y=30\,\mathrm m+\left(250\dfrac{\rm m}{\rm s}\right)\sin45^\circ\,t-\dfrac g2t^2

where g=9.8\dfrac{\rm m}{\mathrm s^2}. Solve y=0 for the time t it takes for the projectile to reach the ground:

30+\dfrac{250}{\sqrt2}t-4.9t^2=0\implies t\approx36.2458\,\mathrm s

In this time, the projectile will have traveled horizontally a distance of

x=\dfrac{250\frac{\rm m}{\rm s}}{\sqrt2}(36.2458\,\mathrm s)\approx6400\,\mathrm m

The projectile's horizontal and vertical velocities are given by

v_x=\left(250\dfrac{\rm m}{\rm s}\right)\cos45^\circ

v_y=\left(250\dfrac{\rm m}{\rm s}\right)\sin45^\circ-gt

At the time the projectile hits the ground, its velocity vector has horizontal component approx. 176.77 m/s and vertical component approx. -178.43 m/s, which corresponds to a speed of about \sqrt{176.77^2+(-178.43)^2}\dfrac{\rm m}{\rm s}\approx250\dfrac{\rm m}{\rm s}.

Help PLEASE!! This is my last question of this QUIZ THAN I'LL BE FREE!!<br> 20 pts!!!!

Answer:

y=0.012x+0.65

Step-by-step explanation:

And again y=mx+c  

we have 4 point given in the question

(50,1.25) ( 100,1.85) ( 150,2.45) (200,3.05)

we can find the M ( gradient/Slope) by using 2 of them with the formula

I am using the first 2 (50,1.25) ( 100,1.85)

\frac{y2-y1}{x2-x1}

\frac{1.85-1.25}{100-50} \\\frac{0.6}{50}

which in decimal form is 0.012

with that cross out the first option as its wrong

now to find c, like in the previous two question, put the m, x and y in the equation and solve for C

I am gonna use the 3rd coordinates for this one (150,2.45)

2.45=0.012(150)+c

2.45=1.8+c

0=1.8-2.45+c

-c=-0.65

c=0.65

So our completed equation is y=0.012x+0.65

The third answer is correct :)
