Question

an arrow is fired directly horizontal off a cliff that is 10 meters tall with a velocity of 65.5m/s.

A. How long is the arrow in the air?
B. What is the range of the arrow?

Answer 1

\[\Delta y= -10 = -\frac{ g t^2 }{ 2 }\]

Answer 2

find t and use in
\[\Delta x = 65.5t\]

Answer 3

\[\Delta y = \frac{ -1 }{ 2 } (g) (t^2)\]

Answer 4

\[\Delta x = Vx(t)\]

Answer 5

\[g=9.8\]

Answer 6

yes

Answer 7

which one is x and which one is y?

Answer 8

i can solve it

Answer 9

r u rhere

Answer 10

h=0.5gt*t or, 10=0.5*9.8*t*t or, t=1.4 sec

Answer 11

range R=65.5*1.4=91.7m

Answer 12

if u need explanation then ask me when u r online
