Answer:

the  \: value \:  of  \: the \:  vertical  \: component \to : \\  (v_v) = 3m {s}^{ - 1}  \\

Step-by-step explanation:

let \: the \: velocity \: be \to \: v \\let \: the \: horizontal \: component \: be \to \: v_h \\ let \: the \: vertical \: component \: be \to \: v_v \\ applying \: the \: pythagorean \: rule \: of \: vectors \to :  \\  {v}^{2}  =  {v_v}^{2}  +  {v_h}^{2}  \\  {v_v}^{2}  =  {v}^{2}  - {v_h}^{2}  \\ {v_v}^{2} = {5}^{2}  - {4}^{2}  \\ v_v =  \sqrt{(25 - 16)}  \\ v_v =  \sqrt{9}  \\ \boxed{ v_v = 3 {ms}^{ - 1} }

GUYS PLEASE HELP
Volgvan

Answer:

10 minutes

Step-by-step explanation:

Since you can do 6 flyers each minute, the rate would go at 6x, with x being minutes. You initially did 80, so the equation for you would be y=6x+80.

Your friend's equation would be y=4x+100, because he initially had 100 done and is now getting 4 done per minute.

If you put the 2 equations in your calculator, the intersection will happen at x=10, showing that you and your friend will have an equal number of flyers at 10 minutes.
