With what initial velocity must an object be thrown upwards so that it will reach a maximum height of 800 feet? Assume the that

Flauer [41]

Answer:

Option b is right.

Step-by-step explanation:

When an object is thrown upwards, the acceleration acting is acceleration due to gravity in a negative manner.

a = -32 ft/sec square

Initial velocity let it be u

Final velocity when it reaches maximum height is 0

Use the formula connecting, u, v, a and s

$v^2=u^2+2as\\0 = u^2-2(32)(800)\\u = \sqrt{64(800)} \\u = 160*0.707\\= 226.27$ ft/sec

Hence we find that initial velocity is 226 ft/sec

Option b is right.

Use square ABCD for this problem<br><br> IF AC=26,find BC.

katen-ka-za [31]

Answer:

x= $\sqrt{338}$

Step-by-step explanation:

$a^2+b^2=c^2$

$x^2+x^2=$ $26^2$

$2x^2=26^2$

$2x^2=676$

/2 /2

$x^2=338$

$\sqrt{x^2} =\sqrt{338}$

x= $\sqrt{338}$

PLEASE HELP I WILL MARK BRAINLEIST

icang [17]

Answer:

25 mm

Step-by-step explanation:

Set up a proportion where x is the number of millimeters for 160 kilometers

$\frac{5}{32}$ = $\frac{x}{160}$

Cross multiply and solve for x:

32x = 800

x = 25

So, 25 millimeters represent 160 kilometers
