Question

( x_{1}=x_{i}+overrightarrow{u_{1}-x} frac{1}{2} vec{a}_{2}^{2} )
( hat{B}=ln int_{1}^{wedge}=vec{v} t hat{j}+frac{1}{2} g t^{2} hat{j} )
( h+v t=frac{g r^{c}}{2} )
( y^{c^{2}}-2 v^{t}-2 h=0 )
( t=frac{+2 v pm 1 sqrt{4 v^{2}+8 g h}}{2 g} )
( 2+frac{v}{g}+frac{v sqrt{v^{2}+2 j h}}{g} )
( t=frac{v}{g}[1+sqrt{frac{1+2 g h}{-v^{2}}}] )
