Impossible Physics Problem?

you divid 32.174 by about 4

Quadratic formula; solve for 'B' using only the positive side with known 'A' , 'C' and 'X'

0. u throw it while it's still

Simply solve [eqn]
\left\{
\begin{align}
y''(t) &= -g \\
y'(0) &= v_0 \\
y(5) &= -30
\end{align}
\right.
[/eqn] for [math]y[/math] and then solve [math]y(0) = 0[/math] for [math]v_0[/math]

Answer is [math]\frac{1}{2} (5 g-12)[/math]

Listen up brainlets:

Distance the ball will travel upwards:
[eqn]H_{max} = \frac{v_{0}^2}{g}[/eqn]

Time the ball will travel upwards:
[eqn]t_{a}=\frac{v_{0}}{g}[/eqn]

From:
[eqn]S = v_{0}t_+\frac{gt^2}{2}[/eqn]

we get final equation (ball moving downwards):
[eqn]H_{max} + 30 = \frac{g(5 - t_{a})^2}{2}[/eqn]

[eqn]\frac{v_{0}^2}{g} + 30 = \frac{g(5 - \frac{v_{0}}{g})^2}{2}[/eqn]

result is ~16 m/s

HAHAHAHAHAHA

Holy fucking shit I can't believe most of you are in university.

This is why this board is trash

no, this is why this board is trash

if you don’t use calculus and instead use a memorized equation to solve this, i am loling at your life

object is always under the same acceleration dipshit

acceleration due to gravity is always pointing down
