A body is projected vertically upwards with a velocity u, after time t another body is projected vertically upwards from the same point with a velocity v, where v < u. If they meet as soon as possible, then choose the correct option

\[t=\frac{u+v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{g}\]

\[t=\frac{u-v+\sqrt{{{u}^{2}}+{{v}^{2}}}}{g}\]

\[t=\frac{u-v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{g}\]

\[t=\frac{u-v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{2g}\]

A body is projected vertically upwards with a velocity u, after time t

1.	A body is projected vertically upwards with a velocity u, after time t another body is projected vertically upwards from the same point with a velocity v, where v < u. If they meet as soon as possible, then choose the correct option
A.	\[t=\frac{u-v+\sqrt{{{u}^{2}}+{{v}^{2}}}}{g}\]
B.	\[t=\frac{u-v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{g}\]
C.	\[t=\frac{u+v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{g}\]
D.	\[t=\frac{u-v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{2g}\]
Answer» C. \[t=\frac{u+v+\sqrt{{{u}^{2}}-{{v}^{2}}}}{g}\]
