Question

$	heta = 45^\circ $

${R_{\max }} = \frac{{{u^2}}}{g} = 1.6\,m$

$\Rightarrow \,u = 4\,m/s$

$u\cos 	heta = 4\cos 45$ $ = 2\sqrt {2\,} \,m/s$

Vedclass · Accepted Answer

$20\sqrt 2 \,m$

Vedclass · Answer

$	heta = 45^\circ $

${R_{\max }} = \frac{{{u^2}}}{g} = 1.6\,m$

$\Rightarrow \,u = 4\,m/s$

$u\cos 	heta = 4\cos 45$ $ = 2\sqrt {2\,} \,m/s$

$S = u\cos 	heta 	imes t$

$	herefore S = 2\sqrt 2 	imes 10$

$	herefore S = 20\sqrt 2 \,m$

A grasshopper can jump maximum distance $1.6\; m$. It negligible time of the ground. How far can it go in $10 \;s$?
