How long did it take to reach the bottom of the slope

mafiozo [28]

To solve this we are going to use the kinematic equation for final velocity: $V_{f}=V_{i}+at$
where
$V_{f}$ is the final velocity
$V_{i}$ is the initial velocity
$a$ is the acceleration
$t$ is the time

We know for our problem that the the velocity at the beginning of the slope is $2.0ms^{-1}$ , so $V_{i}=2.0$ . We also know that the speed ad the bottom of the slope is $20ms^{-1}$ , so $V_{f}=20$ . We also know that the acceleration is $6ms^{-2}$ , so $a=6$ . Lets replace those values in our formula and solve for $t$ :
$V_{f}=V_{i}+at$
$20=2+6t$
$6t=18$
$t= \frac{18}{3}$
$t=3$ seconds

We can conclude that it takes the roller coaster 3 seconds to reach the bottom of the slope.

How can N+4/3=1/3,What is the value of N

ivann1987 [24]

N + 4 / 3 = 1 / 3

Multiply both sides by 3 :

3* ( N + 4 / 3 ) = 3 * ( 1 / 3 )

∴

N + 4 = 1

Subtract 4 from both sides:

N + 4 - 4 = 1 - 4

N = - 3

hope this helps !.

Z varies jointly with y and the square of x. If x=4 when y=−7 and z=−336, find x when z=36 and y=3.

mario62 [17]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\$

$\bf \textit{z varies jointly with y and the square of x}\qquad z=kyx^2
\\\\\\
\textit{we also know that }
\begin{cases}
x=4\\
y=-7\\
z=-336
\end{cases}\implies -336=k(-7)(4)
\\\\\\
\cfrac{-336}{-28}=k\implies 12=k\qquad \qquad \boxed{z=12yx^2}
\\\\\\
\textit{when z=36 and y=3, what is \underline{x}?}\qquad 36=12(3)x^2
\\\\\\
\cfrac{36}{12\cdot 3}=x^2\implies \sqrt{\cfrac{36}{12\cdot 3}}=x$
